BabyLog - Baby Care Tracker
BabyLog is a record book for the busy early months. With a few taps you can log a breastfeed (left, right or both, with a built-in timer), a bottle of formula in millilitres, a wet or dirty diaper with colour and consistency, a nap or night sleep, and, later on, what your baby ate when starting solids.
When you are sleep-deprived it is hard to remember which side you fed on last, how long ago the last feed was, or how many wet diapers there have been today. The home screen answers those questions at a glance, and the timeline and charts help you see patterns over the past week.
Records are also useful to show a midwife, health visitor or pediatrician, who often ask how many feeds and diapers there have been and how the baby is sleeping.
The app runs entirely in your browser. What you enter is saved only on this device.
How to use BabyLog
- Register your baby. Enter your baby's name and birthday. The home screen then shows their age in days or months. On the web, a short disclaimer appears the first time and stays available in Settings.
- Log a feed. Tap Feeding and choose left breast, right breast, both, formula or mixed. Use Start Timer and Stop Timer to time a breastfeed, or pick a formula amount in ml. Adjust the time if you are logging it afterwards, add a memo and save.
- Log a diaper. Tap Diaper and choose pee, poop or both. For poop you can add the colour (such as yellow, green, brown, white or red) and consistency (watery, soft, normal or hard).
- Log sleep. Tap Sleep, set when your baby fell asleep and, if known, when they woke up. Leave the end time empty if they are still sleeping. Mark night sleep to tell it apart from naps and optionally rate the sleep.
- Log first foods. Tap Baby Food, enter the ingredients and how much was eaten, and tick First Time Food or Allergy Reaction Observed when relevant.
- Check today. The home screen summarises today's feeds, diapers, sleep and foods, and shows how long ago the last one happened.
- Review and correct. Open the Timeline to see records in order and edit or delete any of them. Statistics show today's totals, the past seven days and charts of feeding intervals, sleep and food.

What parents commonly track in the first year, and why
Feeding
Newborns feed often, commonly 8 to 12 times in 24 hours in the early weeks, and many feed in clusters at certain times of day. Pediatric guidance generally recommends feeding in response to hunger cues, such as rooting, sucking on hands and stirring, rather than strictly by the clock. Noting the side you finished on helps you start the next breastfeed on the other side. Your midwife, health visitor or pediatrician can tell you what is normal for your baby, especially in the first days.
Wet and dirty diapers
Diapers are one of the simplest signs that a baby is getting enough milk. After the first few days, many sources describe around six or more wet diapers a day as reassuring. Stools change from dark meconium to yellow or mustard in breastfed babies and often a firmer, tan or brown stool in formula-fed babies. Green stools are usually harmless. Contact a health professional promptly if stools are white, pale grey or chalky, if you see blood or black stools after the first few days, or if wet diapers become noticeably fewer.
Sleep
Babies sleep a lot but in short stretches, and patterns change quickly over the first months. For safer sleep, health organisations advise placing babies on their back for every sleep, on a firm, flat mattress, in a cot or bassinet without pillows, bumpers or loose bedding, in the same room as a parent for the first months. Logging sleep can show emerging routines, but there is no single right amount for every baby.
Starting solid foods
Many health authorities suggest starting solid foods at around six months, alongside continued milk feeds, when a baby can sit with support and shows interest in food. Introducing one new food at a time and noting it makes it easier to link any reaction to its cause. Advice on common allergens has changed in recent years, so ask your pediatrician or health visitor how to introduce them for your baby. Seek emergency help for swelling of the face or lips, difficulty breathing or widespread hives.
Sharing the load
A shared log helps when parents or carers take turns, so everyone knows when the last feed or diaper change was. Bring your records to check-ups: concrete numbers and times are much easier to discuss than impressions from a tired memory.
Frequently asked questions
Where is my data stored?
Only in this browser on this device. There is no account and nothing is uploaded. Clearing browser data, using a private window or switching browsers or devices means your records won't be there.
Can two parents share the same log?
Not on the web. Each browser keeps its own records, so entries made on one phone or computer don't appear on another.
Can I record bottle amounts in ounces?
No. Formula amounts are recorded in millilitres.
Can I add a record I forgot?
Yes. Change the time on the record screen before saving. You can also edit or delete records from the Timeline.
Does BabyLog tell me if something is wrong?
No. It records what you enter and shows totals and charts, but it does not assess your baby's health. Contact a health professional if you are worried.
How is the web version different from the phone app?
Logging, the timeline and statistics work the same. The iPhone and Android apps can also send feeding and diaper reminders at an interval you choose; the web version sends no notifications.
Limitations of the web version
- No feeding or diaper reminders on the web
- No sharing between devices or caregivers
- Formula amounts in ml only
- Data stays in one browser and is not backed up
