> If you don’t know why it matters how many diapers there have been in the last 24 hours and what kind of mess was in there, along with how often and how much milk was consumed, you’ve obviously not been the primary caretaker of an infant recently.

I don't want to downplay your software and your effort but my wife and I raised two wonderful baby girls without any app tracking how many diapers we changed or how many poo they did. We only had to be a bit more "strict" on weight-gain tracking for the 1st one during her first 2 months or so because she was born quite small and we had some issues breastfeeding her at the beginning. I understand there might be situations where it is useful to track some data of the infant but I would say it's just if there is some underlying condition.
