Your baby’s first year, gently explained

Short, calm updates for tired parents. Read a letter at the 3 a.m. feed and know what this week is about.

A letter from your baby

Each week your baby “writes” you a short, voiced letter about what they are learning and feeling right now, in their own little words.

Your baby, illustrated

Choose hair, skin tone and outfit so the character in the app looks like your little one. Nothing about their appearance leaves your phone or your iCloud.

Milestones, week by week

See what is typical for your baby’s age, from first smiles to first steps, and tick milestones off as they happen. Every baby goes at their own pace.

Play ideas on video

Short, gentle activities and explainer videos matched to your baby’s week, so you always have something simple to try together.

Private memories

Add photos to milestones and keep your baby’s letters. They stay on your iPhone and in your own private iCloud, never on our servers.

Calm, not worrying

No scores and no comparisons with other babies. If something worries you, the app always points you to your paediatrician.
