01 · LITTLEST THINKS

Littlest reads your child's own patterns, not a generic chart, and only speaks up when there's something worth knowing and something you can do about it.

How it works

Gets smarter every day

Every feed, nap and conversation teaches Littlest more about your child. There's no parenting app built like this.

1

You log, or you just chat

A tap, a timer or a sentence. Feeds, sleep, nappies, solids, milestones. Tell Littlest what's going on in the chat and it remembers.

2

Littlest learns your child

Patterns are measured against your child's own normal, for their age, not a textbook average. A cold or a trip is a reason, not a trend.

3

You get one clear next step

What's normal, what's changing, and one thing to try. Or a plain "nothing needs doing". It gets smarter with every day you use it.
