We used to keep a paper log by the crib. I found this app by chance and we switched the same day. So much easier than the notebook ever was.

As a stay-at-home dad, I can show my partner exactly what the day looked like. Feedings, naps and everything in between are all there.

The growth charts are beautiful and actually useful. I showed them to our pediatrician and she was impressed.

My husband and I are in the same family group and records sync in real time. When he feeds her, I see it on my phone immediately.
