The idea

New parents tap to log feeds, diapers and naps, and the other parent sees it instantly on their phone. A handoff screen shows what happened on the last shift at a glance. It helps sleep deprived parents stop asking "when did she last eat?"

PROMPT 1 OF 3

Build a mobile app called Newborn Shift Log. One parent signs up, adds the baby by nickname, and invites a partner. The home screen has three big buttons: Feed, Diaper, Sleep, plus time since the last feed shown large.

PROMPT 2 OF 3

Feed logs side or bottle amount and start and end time; Diaper logs wet or dirty; Sleep has a start and stop timer. Sync in real time with Supabase so both phones update. Add a Handoff screen summarizing the last six hours and a dark mode that is easy on the eyes at night.
