One baby. Two phones. One record.
Feeds, nappies, sleep, temperature and growth, logged one-handed in under five seconds, and on your partner’s phone straight away.
Free to log. Free to share. Permanently.
Currently available in the UK.

A logbook two people keep together.
One of you writes down a feed, a nappy, a sleep, a temperature or a measurement. It is on the other phone a moment later. That is the whole idea.
It is built for a couple sharing the care of one baby through the first year. Not a community, not a course, not a programme to follow. There is no feed to scroll and no home screen to get past: it opens on today, every time.
When the signal goes, you keep logging. The app says the record is out of sync rather than showing numbers that may no longer be current.

Under five seconds, one-handed.
Big buttons, quick times for the feed you forgot to log, and nothing between you and today.
Three things that make it different.
It agrees with the red book
Measurements are plotted on the UK-WHO charts, from the same reference data behind the centile charts in your red book. For a baby born early it reads at corrected age. What you are shown at a weigh-in and what you are shown in the app do not disagree.
It never reaches a verdict
Lullabean records what you enter and shows the arithmetic behind any figure it suggests, so you can check it and change it. Where it shows reference material it quotes the published NHS source and names it. It draws no conclusion about your baby. That conversation belongs to your health visitor or GP.
Sharing is free, permanently
The second parent is the premise of the product, not an upgrade. Logging and the shared record are free for both of you, with no trial, no card and no per-parent charge. Anything that is free when you download it stays free for you.
No health guidance is ever sent as a notification.
Start the record tonight.
One of you creates the logbook and sends an invite. Both phones then hold the same record, and either of you can write to it or correct it.
