I’d use something that already exists:

• https://life-notes.fr/
• https://github.com/babybuddy/babybuddy
• https://github.com/BabyTracker/baby-tracker

The focus of the latter two is slightly off, but it would work.

Actually, I’d probably not add a use-specific thing unless I needed something specific it offered. I’d just pop up another page on our shared wiki to track things, or put it in a synced note app.

Syncthing is another nice option for syncing Obsidian notes.

You’ll want to use Syncthing-fork on Android.

I’ve seen people try wax, but I have no idea how well it works.
