American families rarely raise a baby in one place with one caregiver. Grandparents in another state, a nanny during the week, co-parents splitting time — Lunara keeps one shared, real-time record instead of scattered notes and group texts. Whichever state a caregiver is logging in from, the data stays in sync.
- Growth charts on the same WHO percentile standard your pediatrician uses, wherever you're seen
- Vaccine tracker aligned to the CDC's recommended immunization schedule
- Multi-caregiver sharing built for families spread across cities and states
- Available free on iOS and Android nationwide — no regional restrictions
Having a baby in the United States
Raising a baby looks different depending on which part of the country you're in — healthcare access, climate, and even everyday parenting norms vary widely from state to state. Families also move between states more often than in most countries, which means a baby's care record frequently needs to follow them from one pediatrician to the next, not stay locked inside a single clinic's system.
Nationally recognized children's hospitals are spread across the country — Boston Children's Hospital, Children's Hospital of Philadelphia (CHOP), Texas Children's Hospital, Cincinnati Children's, and Children's Hospital Los Angeles (CHLA) among them. Wherever you're seen, your pediatrician is almost certainly working from the same WHO growth percentile standards and CDC immunization schedule Lunara tracks against, so your baby's record stays comparable no matter where you move.
Climate varies enormously across the US — Alaska's long winters, the Southeast's humidity, the Southwest's desert heat, the Northeast's four distinct seasons — all of which can affect a baby's sleep environment differently depending on where you live. Parenting culture varies just as much, region to region and family to family. Lunara doesn't assume a single "American" parenting style; its AI insights adapt to your baby's own logged patterns, wherever you're raising them.

What US parents say about tracking with Lunara
"We moved from Texas to Oregon when our son was four months old. Lunara's sleep log came with us — his pediatrician here picked up right where the last one left off."
"The CDC-aligned vaccine reminders are what sold me. I never have to double check the schedule myself before a visit anymore."
"My mom lives three states away and logs naps when she's watching the baby. It all shows up in my app the same day — no more group text updates."

This isn't a partnership claim, just a shared reference point that keeps Lunara's charts comparable to what your pediatrician shows you, wherever you're seen.
Climate varies enormously across the country — from Alaska's long winters to Southeast humidity to Southwest desert heat — and temperature is a genuine factor in sleep quality.
