to your baby's Red Book
Every baby born in the UK is given a Personal Child Health Record — universally known as the "Red Book" — the official physical booklet where growth, vaccines, and health visitor reviews are recorded. Lunara isn't a replacement for it; it's a genuinely useful companion for the day-to-day tracking that happens between appointments, so you walk into every health visitor check or GP visit with a clear picture already in hand. Because the NHS is free at the point of use, that clinical record-keeping is universal across the UK — Lunara simply makes it easier to stay on top of between visits.
- Growth charts on the same WHO percentile standard used in your baby's Red Book
- Vaccine tracker you can align to the schedule set out in your baby's Red Book
- Multi-caregiver sharing built for grandparents and family across the country — or abroad
- Available free on iOS and Android across every home nation — no regional restrictions
Having a baby in the UK
The UK is made up of four home nations — England, Scotland, Wales, and Northern Ireland — each with its own NHS structure (NHS England, NHS Scotland, NHS Wales, and Northern Ireland's HSC), but a shared core experience for new parents: free-at-the-point-of-use maternity and infant care, a Health Visitor who carries out home visits and runs local baby clinics at set ages, and the Personal Child Health Record — the "Red Book" — that every baby is given at birth.
Growth is tracked on WHO percentile standards, the same ones Lunara's growth charts use, and immunizations follow the schedule set out in your baby's Red Book, which Lunara's vaccine tracker can be aligned to. Because the system is universal rather than insurance-dependent, nearly every UK family goes through the same core touchpoints — the new birth visit, the 6-8 week check, and the 1-year and 2-2.5 year reviews.
Lunara's AI insights adapt to your baby's own logged patterns wherever in the UK you call home, and stay in sync with grandparents, partners, or childminders — whether they're a few streets away or in a different part of the country entirely.

What UK parents say about tracking with Lunara
"I used to scramble to remember feeding times before health visitor appointments. Now I just show her the weekly digest — it's so much easier than trying to recall a whole week from memory."
"Our GP uses the same WHO growth curves Lunara shows us, so I can actually follow along at every checkup instead of just nodding along."
"My mum minds the baby one day a week up in Yorkshire while I'm at work in London. Lunara means we're never out of sync on his routine."

Most baby tracker apps popular with UK parents, like Huckleberry or Glow Baby, focus mainly on sleep. Lunara tracks sleep, feeding, growth, milestones, and vaccines together, and uses AI to connect all of that data into one plain-language weekly digest — not just separate logs.
Health Visitors are NHS nurses who carry out home visits and run local baby clinics at set ages — including the new birth visit, the 6-8 week check, and the 1-year and 2-2.5 year reviews. Lunara's logs can be a genuinely useful thing to bring along.
Yes — Lunara supports multi-caregiver sharing, so a grandparent, relative, or childminder anywhere in the UK — or abroad — can log and view the same baby's data in real time alongside parents.
