Family Story: Six Months of Tracking Baby Sleep

Tuesday, September 23rd, 2008

Logan’s parents tracked their son’s sleep schedule from 1 month to 7 months old. They wrote about their experience on their blog and offered up a few reasons that they loved their tracker:

  • Allan could check from work how our day was going
  • I could see that the hard work put into sleep training was paying off; I needed all the motivation I could get!
  • Even though it only took a few minutes a day people thought was a supermom when they saw our site ;)
  • When Grandma and Grandpa babysat I could look at the last few days and say with great accuracy what to expect from sleep, feeding and diapers (’He had a good nap this morning so he’ll likely take about an hour and a half nap around two, around 6:30 he’ll want to cuddle and might sleep for thirty minutes…’) Truly data driven parenting.
  • The first three months are fuzzy in my mind. It’s nice to look back and see that we made it through it!
  • I love analyzing data and this gave me a little project :)

These are all great reasons, but I’m particularly partial to the last one. Curiosity is what drove me to create Trixie Tracker, so I’m always thrilled to hear it is helping other parents satisfy their own curiosity.

You can discover amazing patterns in your child’s schedule if you simply observe. Become a parent scientist for a few days and see what you learn. It’s worth trying and it’s free!

How One Mom used Trixie Tracker to Help with her Baby’s Sleep Schedule

Saturday, May 24th, 2008

I asked parents how Trixie Tracker had helped them. Jena, proud mother of four boys, wrote to let me know how Trixie Tracker gave her the information she needed when trying to address her son’s chronic sleep and napping problems. Here’s what she said:

Nico is my 4th son but the first one whose sleep was so out of whack. He slept 8hrs/night straight for the first 5 months but hardly napped and when he started napping, his night times went awful.

I started tracking him at 7 months using TT so I could see any patterns developing, see how much actual sleep he was getting, and have records to back up what I suspected. By 20 months, even my pedi had to agree that he was not getting an average amount of sleep and that it was time to start delving deeper into things and we were referred to a developmental pedi. After talking to him and a behaviorist pedi, we were finally referred to a sleep specialist neurologist. I was able to show him our records for months so he could see the patterns (or in our case, the lack of them) and how long it would take to put him down at night.

He was able to see what our problems were and see that we really had done everything behaviorally that we could do and recommended putting our son on melatonin. With that, his average sleep has gone from 9hrs/day to almost 10½hrs/day but none of that would have been nearly as easy to get done if I hadn’t had all the records right at my fingertips to show the doctors at every step of the way. My son is much happier now that he gets more sleep and we are as well.

I really can’t imagine trying to have kept a sleep log on my own to be able to show the doctors what we were dealing with so TT has definitely been, if not a life saver, a sanity saver for me.

Parents almost always know when something is a little off with their babies, but sometimes it’s hard to for them to put their finger on it. That’s where Trixie Tracker really shines. It connects the dots and shows you the patterns because it’s impossible to keep all that information in your head – especially if you are sleep deprived.

I’m glad Trixie Tracker was able to back-up Jena’s parental instincts so she could help her son and get her whole family back on a good sleep schedule. Jena, thanks so much for sharing your story.

How does Milk Inventory Work?

Monday, March 20th, 2006

Milk Inventory is designed so you can keep track of your milk production. It does two important things:
1) Links containers to specific pumping sessions (and optionally, feeding bottles)
2) Tells you how long and where a specific container of milk was stored and its volume.

Part 1. Creating Milk Inventory

When you record a pumping session, you have the option of tracking the milk as virtual inventory. To do this, you assign milk to different storage containers (bags or bottles) and indicate how much milk you are putting in each container.

Inventory #’s are Unique
Inventory works by linking an unique inventory # to a physical container (bag or bottle) for a specific period of time. Once that container is used, the # is retired. You can certainly reuse the physical bottle, but it’s going to get a new # the next time you fill it up.

Tip: Don’t want to start with container #1? If you key in a higher number, for example 100, Trixie Tracker will automatically increment from the highest number and display 101, 102, 103, 104 the next time you pump.

Pump and Pour
When you are done pumping, divide your milk into storage container(s). Each container will get an inventory #.

Assign Numbers
On the ‘Add Pumping’ form, you’ll see that Trixie Tracker automatically generates sequential inventory #’s. Assign one of those #’s to each physical container, and indicate the volume.

Have your Marker Handy
Now, instead of the date and time, you write the inventory # on the storage bottle/bag.

You’re done
That’s all there is to it. You can now view your Inventory page and get a summary of everything that’s in your freezer or fridge.

Part 2. Inventory and Feeding Bottles

If you are tracking Bottles and you have Milk Inventory, you’ll notice that your inventory automatically shows up on your ‘Add Bottle’ form. This lets you manage your inventory at the same time you add a bottle.

No Need to Toggle
At first you may want to toggle back and forth from Bottles and Inventory when adding a bottle. However, this is not necessary because there’s not a volume relationship between the two — only a link relationship. The software was specifically designed this way to simplify the inventory-to-bottle process.

Here’s an example of how the process should work
For this example, assume that you pumped 4 oz into container #10 and it was stored for some period of time.

1) When it’s time for a bottle, make the physical bottle first (go ahead and pour the milk in).
2) On your ‘Add Bottle’ form, set the starting volume
3) On that same form there’s a list of the three oldest container #’s. (Let’s assume it’s #10, #11 and #12.) If you added milk from one of those container #10, click to add it. Add additional containers if needed. If you finish a container #, check the box to retire it.

You’re done
That’s all there is to it. You can now see links between specific bottles and pumping sessions, you know how long and where the milk was stored, and you were also able to retire containers from the ‘Add Bottle’ form so you don’t have to do it manually on the Inventory page.

Guest Password Access and Public Sharing

Monday, February 6th, 2006

Trixie Tracker has two ways that you can share your site with friends and family. These features allow you to give another person ‘view-only’ access to your site. You also get to determine which pages your guests may view.

Guest Password Access
This allows anyone to view your site if they know your site address and guest password. You set the password, and pass it out to your friends and family. Everyone can sign in with the same password to see the pages you have made public.

Public Sharing
This is just like Guest Password Access except there is no password required. Anyone can view your site if they know — or guess — your Trixie Tracker site address.

You can have both Guest Password Access and Public Sharing set up at the same time. And you can make different pages private for each type of sharing.

The default setting for both kinds of sharing is OFF.

guest access off

If you want to activate either type of sharing, you’ll check the box to Allow Sharing, and then you’ll choose what features your guests may view.

guest access on

Security and Privacy
If you decide to allow Public Sharing, remember that ANYONE could guess your Trixie Tracker site address. You should probably not enable this feature unless you have no concerns about other people looking at your site.

If you decide to allow Guest Password Access, please use a good strong password. You don’t want your password to be guessable.

Day/night switch on Full Sleep chart

Friday, February 3rd, 2006

There’s a new link on the Full Sleep chart that lets you toggle back and forth between the daytime view and the overnight view. All it’s really doing is shifting the position of your data by 18 hours. The daytime view (the normal view) runs from midnight to midnight (00:00-23:59). The overnight view runs from 6pm to 6pm of the following day (18:00-18:00). This allows you to look at your overnight sleep as a visually unbroken span.

This new overnight view may be preferable to some users, but I want to point out that TT still bases all its calculations on calendar days (except of course for the overnight sleep time calculation). The reason I mention that TT uses calendar days is because the overnight calculation spans two calendar days. If *either* calendar day is marked as ‘ignore’, then TT can not calculate an overnight sleep time.

Day/night toggle

What this means is that one ‘ignored’ day in the daytime view shows up as two ignored days on the overnight view. Two consecutive ignored days in the daytime view shows up three consecutive ignored days in the overnight view and so forth. Basically, if you use the ‘ignore’ feature you will always have more ignored days in the night view than the daytime view.

Ignore this day

Friday, February 3rd, 2006

Because of some problems with Sleep Stats grabbing bad data (from vacation days, weekends off, and otherwise incomplete days), I made some pretty significant changes to the way Sleep data is handled. You can now tell TT to ignore any date when calculating averages and stats.

There is a new button on your Sleep Summary page that appears under the Sleep Journal area. It says “Ignore this day”. (Hold your cursor over it to get a longer description.) Clicking this button tells TT to ignore this day when crunching your data.

Sleep Ignore Day example

After you have marked a day as ‘ignore’ the button changes to red, and says “Include this day”. If you decide the data on that day isn’t all that bad, you can easily choose to include the day in your averages again.

Sleep Ignore Day example

Days marked as ‘ignore’ will show up with a red description on your ‘Full chart’ page, so you can use your full chart to see how many days you are ‘ignoring’.

Here are a couple of tips:

  • If a day is already listed as “no data”, it’s not necessary to ‘ignore’ the day. TT already excludes days with no data.
  • Look at your stats page to see if bad data is being including in your averages. Clicking “view” from the stats page will take you directly to the day in question and you can easily mark it with ‘ignore’ if necessary.
  • Excluding days is a Sleep only feature for right now. Eventually the other telemetry will catch up, but I really have to get the site launched first

[Update]
I changed the way ‘ignored’ days show up on the chart. The colors for ignored days are now grayed back so you can visually ignore them as well computationally.

Faded Ignore Day example

Nap Totals

Friday, February 3rd, 2006

TT now separates out naptime from the total sleep-time. You can see this on the sleep summary and the home page.

Here’s how the nap total is calculated
:
Any sleep entry where the ‘Fell asleep‘ time is between 8am and 6pm is counted as a nap. This is the inverse of how the overnight sleep-time is calculated (6pm-8am).

This may not be the perfect solution. The advantage to defining a specific time span is that you can accurately compare data to the group average (forthcoming). The disadvantage is that there may occasions when your data steps outside the defined area. For example, if your child gets up at 5am and takes a morning nap from 7:30 to 8:30, that nap wouldn’t be counted toward the daily nap total (it would actually get added to the overnight sleep total).

Even if each user were able to define their own day and night times (for example, day: 6am-5:40pm or night: 7:15pm-8:30am) it is likely that you would run into exceptions from time to time that would cause the calculations to be off.

Eventually I plan to develop a smart algorithm that will distinguish naps from overnight sleep. In the meantime, I think this solution will work — especially as your child gets older and on a better nap schedule.

One note: Please don’t change nap or sleep times to force them to be counted as either naps or overnight. It might make your nap or overnight totals ’seem’ a little more accurate for the day, but it’s actually damaging the integrity of your data over the long run. The best thing to do is to keep as accurate records as you can, and wait for TT to get smarter :) thanks!

Pumping inventory

Friday, February 3rd, 2006

You can now track your pumped milk with virtual inventory. There’s a new addition to the “Add Pumping” form that allows you to assign milk to a container with just one extra click. Then, instead of writing the date and time on the storage bottle/bag, you write the TT inventory #.

Labeling your milk inventory

Container detail

Fridge detail

Adding inventory numbers is totally optional, but it requires so little effort that I would recommend trying it at least once or twice. And if you choose to let TT keep inventory, some pretty cool things can happen:

  • Just glance at your Inventory page and get an immediate summary of the total volume of milk in your fridge and freezer.
  • Did you have spicy Thai food and a beer one evening before you pumped? Add a comment to that pumping session. Inventory will automatically grab any associated pumping notes and link it to the correct container.
  • If you pump all the time and don’t have production worries, you may just want to track one session every couple of days as an audit. It will give you a very precise figure for the milk turnaround in the fridge or freezer.
  • If you store extra milk in the freezer, tag it and forget about it. One glance at your inventory page will tell exactly how old each container is, and which container you should pull out first.

Consider this a placeholder post. Inventory still needs a bunch of documentation, but I was anxious to get it up. Please use this post to report problems, make suggestions, comments etc. thanks!

Btw, I’d like to recommend Milk Week on the Trixie Update if you haven’t seen it yet. I had a fun time putting that series together.

Sleep Probability Chart

Monday, November 28th, 2005

The Sleep Probability chart uses a gray scale to display the probability of your child being asleep at a certain time of day for the selected dates. Areas of high contrast (black and white) mean your child is on a predictable schedule. Areas of low contrast (light, middle and dark gray) mean a less regular schedule. A uniformly gray chart would mean a completely random sleep schedule.

Sleep Probability Chart for a Newborn (birth to 1 month)

Sleep Probability chart for an individual child (1st month)

6 Months Old

Sleep Probability chart for an individual child (6 months old)

12 Months Old

Sleep Probability chart for an individual child (12 months old)

Essentially, this chart shows your child’s sleep schedule by compressing daily sleep charts into one image. This kind of compression is extremely good at showing how patterns form and evolve over time. For example, it can help you identify the average bedtime or realize that your child is transitioning from 3 naps/day to 2 naps/day.

The number of gray scale values depends on the number of days in your chart. If you have two days in your chart, then there will be three colors: black, 50% gray and white. The reason is that the different possibilities for being asleep at a given time for the two days would be:
2/2 (100% – asleep both days at a given time),
1/2 (50% – asleep one day, not the other at a given time) and
0/2 (0% – asleep neither day at a given time)

The more days in your sample, the more possible gray scale values. So if you have a months worth of data (31 days max), there will be 32 shades of gray:
(0/31 through 31/31). This would be approximately 0% black, 3% black, 6% black, 10% black, etc…

More about Solids

Wednesday, November 9th, 2005

I’m excited about the reaction to Solids. I really do enjoy working on Trixie Tracker and it’s always satisfying to add a new feature that gets such a strong response.

I want to point out that Solids Telemetry came about 18 months too late for Jenn and I to use with Trixie. As a result, I developed it based on the memory of what our needs were at the time. If I’ve missed (or forgotten) some important issue, I definitely want to hear about it. User feedback is very much appreciated!

Here’s a couple of thoughts about Solids:

1) Why aren’t there any measurements?
It was too hard to quantify the amount of a given type of food. Take bananas for example. Any of the following measurements would make sense:

  • a jar
  • a few slices
  • half a banana
  • 4 ounces
  • 2 spoonfuls
  • 1/4 cup
  • a bowl
  • 55 grams
  • a taste, etc

I couldn’t figure out a way to quantify these various units so that a daily total (of all foods) could be added up. Therefore I decided to just leave out amounts completely.

However, someone asked yesterday about maybe just limiting the units to jars (since most folks start with jars of baby food), and listing the total amount (of jars) per meal. TT could then add up jars per day. Another possibility would be to provide space to write in the quantity per food item (i.e. “a few spoonfuls” or ”55 grams”) but have it simply be a description — TT would not add the quantities up.

Both of these are possible, but I’m not going to make any changes yet. I’d like to see how people use the program first. The golden rule is that if enough users ask for a certain feature, it will probably eventually get added in :)

2) Integrating all food (Nursing, Bottles, Solids)
I know there are now three different telemetry that keep track of sustenance. And I know that they should hook together somehow so that you can see how nursing relates to bottles relates solids (relates to sleep etc). I’m not totally sure how to address this, but it’s something I have been thinking about. I think the eventual answer is going to be some kind of redesign of the TT home page that will be more flexible and can assemble various telemetry into one daily chart.

Thanks again for everyone’s help! I’m definitely interested in learning how this Telemetry works out. I would have liked to have it when Trixie was little because we had an egg problem. We’re confident now that it’s only a sensitivity and not an allergy, but it took us a while to come to that conclusion (partly because I didn’t keep any records!).
