What's different

Designed for parents, not metrics.

Most milestone trackers feel like a test. Tendling is built around how parents actually parent — paying attention to the small things, then knowing when one of them is worth a conversation.

At their own pace

The opposite of "is my baby ahead?" optimization. Every kid blooms in their own time. We help you notice the small wins, not score them against averages.

Corrected age, automatically

For babies born preterm, Tendling adjusts the milestone timeline based on gestational age, per AAP guidance. Sliding correction window through age 2 (or age 3 for very preterm). No spreadsheets.

Plain language, not jargon

Tap any term — Cognitive, Fine motor, Act-early — to see what it actually means in everyday words. A built-in glossary translates the pediatric vocabulary parents are expected to already know.

Made for the conversation

One tap generates a clean visit summary you can hand to your pediatrician at the next appointment. Patient header, milestone coverage, act-early items grouped by age threshold. No exporting CSVs.

Find specialists nearby

When something needs a closer look, find pediatric specialists in your area — speech pathologists, OTs, PTs, developmental pediatricians, audiologists. Real US-licensed providers from the NPPES registry.

Built on CDC science

Every milestone comes from the CDC's "Learn the Signs. Act Early." catalog (2022 update). Used by pediatricians for over twenty years. The act-early indicators are pre-flagged at the right thresholds.

How it works

Three small habits, that's it.

Tendling fits into the rhythm of being a parent. No daily quizzes, no notifications guilting you. Just the moments worth noticing.

1

Add your child

Just date of birth, sex, and (if applicable) gestational age. Takes 30 seconds.

2

Notice and log

Tap a milestone when you see it. Mark Observed, Emerging, or Not yet. No pressure to be exhaustive.

3

Talk with your pediatrician

When something feels worth bringing up, share a clean summary at the next appointment.
