One App. Every Baby. Zero Mix-Ups.
"Wait, was that Arlo's feed or Nora's?" It's the question every parent of more than one young child eventually asks themselves at 2am. A general baby tracker app that only half-separates two children's data makes the problem worse, not better. Lunara's baby tracker app multiple babies support was built so that question never has to come up — each child has their own log, and switching between them takes one tap, not a mental reset.
How to Add a New Baby in Lunara
Adding a baby tracker app add new baby profile doesn't touch anything that already exists. Here's the full flow:

"Arlo's 847 log entries stayed exactly where they were when we added Nora." — Priya M., mum of 2
Separate Logs for Every Child
Every entry — for every child — completely separate. The American Academy of Pediatrics (AAP) recommends keeping vaccine and health records for each child separately; Lunara does this automatically across all ten tracking categories.

Baby Tracker for Twins: Two Babies, One View

Last sleep: 2h 14m · 3:20 AM
Twin B — Nora
Last feed: 90ml · 7:08 AM
Last sleep: 1h 50m · 4:05 AM
- Separate sleep logs — know exactly who woke at 2am
- Separate growth charts — track each twin's weight independently
- Side-by-side comparison: tap to see both babies' last 24h at a glance

"We have 18-month-old twins. Lunara is the only tracker where I can actually tell who had what, when, from which parent."
