I found this app <a href="https://play.google.com/store/apps/details?id=com.glow.android.baby">baby tracker</a> that has been super helpful and thought i would share! It shows you patterns for feeding, sleeping, pooping. How often, least/most per week. It helps give you an idea as to when to feed them and what amount they usually take. Also what time they sleep best! You can also add notes each time you track. Once the free trial is over you have to but the full app to access the chart tracker part but super useful when it's free at first!
