Uncover Patterns with the Sleep + Feeding Chart

We just released a new feature which combines naps, bottles and nursing into one monthly sleep and feeding chart to help you better understand the relationship between those activities.

For example, the overlay chart can help reveal whether feeding at a specific time in the evening corresponds to when your baby actually falls asleep. You might find that feedings usually occur an hour before falling asleep. If you’re trying to target a certain bedtime, you’ll know when to nurse or give a bottle.

New Mobile Trixie Tracker Optimized for iPhone and Android

The latest version of Trixie Tracker baby tracking software has been completely rebuilt and optimized for a fast, easy-to-use mobile experience. The new Trixie Tracker looks great and works well on iPhone, Android, iPad and tablets.. Matter of fact, it looks great on any modern mobile device, so try it out for free.

Trixie Tracker Mobile has always had a simpler, streamlined screen for entering data, but you can now view all the powerful visualizations that are available in the desktop version. It’s fun to see your full sleep charts and sleep probability charts right in the palm of your hand.

And because Trixie Tracker is a web application, you can view your charts and records simultaneously from multiple phones. That means you and your spouse (or caregiver or grandparents) can all peek in to check when the baby is sleeping.

You can’t do that with standalone native apps where your data is locked up in a single phone. In a nutshell, Trixie Tracker is designed for sharing. We hope you like the new Mobile Trixie Tracker.

Sleep Tracking with Daylight Saving Time

Daylight Saving Time transitions will result in your main charts appearing to be an hour off. This issue only relates to the display of your charts, and it doesn’t affect your underlying data. Here’s a few notes to help you through the weekend.

Daylight Saving Time Summary

  • Trixie Tracker will handle the time change automatically. You don’t need to do anything.
  • Your charts will be off until Monday. There’s no graceful way to map 23 hours or 25 hours to a 24-hour time scale. It’s like trying to park an 11-foot car in a 10-foot garage.
  • The Sunday chart will continue to be shifted by an hour

Falling Back

In the fall, it’s extremely difficult to tell software which 1:50 am you are talking about when there are two times that exactly match that description. To avoid this problem, please record events in real-time during the transition hour (and avoid editing them afterwards).

Springing Forward

In the spring, the transition is easier. Recording real time events shouldn’t be affected because we skipping ahead, and the times never overlap.

How does Milk Inventory Work?

The Milk Inventory feature is designed to track breast pumping and 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

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.

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.

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

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.

Track breast milk with pumping inventory

You can now track breast 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 #.

Do you know how much breast milk you have?

Benefits of tracking breast milk

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 and track breast milk, 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.

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

The Sleep Probability chart in our baby sleep tracker 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.

6 Months Old

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…

Sleep Scatterplot

Sleep patterns of a 7-month old

The scatter plot shows a distribution of sleep and awake entries. It’s very good at showing patterns that aren’t evident in the regular day-to-day sleep chart.

Scatterplot with vertical trend

30 days of sleep data

The chart shows 30 days of data, which are divided into three color groups. Plots in the most recent 10 days are solid. Plots in the middle 10 days are faded a little bit, and the oldest plots are faded even more. This lets you compare recent patterns to older patterns on the same chart.

Consistency in duration of nap

Horizontal patterns in your chart indicate consistency in the length of a nap (or awake entry).

Consistency in time of day

Vertical patterns indicate consistency in the schedule of naps (or awake entries). The example below contains a vertical column of plots around 8:00pm. This indicates a very successful, consistent 8:00pm bedtime. It also shows that the child usually sleeps through the night — but not always.

Clusters of naps

‘Clumped’ patterns indicate consistency in the schedule and length of naps (or awake entries).

First seen on the Trixie Update

This chart is modeled after a sleep analysis story posted on The Trixie Update a while back.
