The parenting handbook for 3 a.m.

Quick-reference parenting answers for babies, toddlers and preschoolers: health checks, milestones, sleep and safety. Short, sourced from AAP, CDC, NHS and WHO guidance, and dark enough to read without waking anyone.

How to use this handbook

Every health page leads with the same three coloured tabs: a red triangle for call 911 now, an amber square for call your pediatrician today, and a green circle for usually fine to watch at home. The shapes differ as well as the colours, so they still read in dim light or with colour-blindness.

Pages open in night mode because most lookups happen during a feed or a wake-up. Tap the sun icon for day mode. Tools remember what you enter (your baby's wake-up time, milestone ticks, childproofing progress) on this device only, and you can clear it anytime.

Nothing here replaces your pediatrician. We summarise what the American Academy of Pediatrics, CDC, NHS and WHO say so you can decide faster whether to call, and what to ask when you do. See how we source.

When the baby's finally down and you want something other than wake windows, ahaboo beats doomscrolling: narrated explainers, like why the Moon changes shape, you can poke at.
