A little love. A little progress.
Every little step counts.
LittleSteps is a gentle tracker for premature babies — growth, milestones and daily care on corrected age, at your baby’s own pace.
Made with preemies in mind — and just as lovely for full-term babies.
Free corrected-age calculator below — no sign-up needed.
Free tool
Corrected age calculator
Enter your baby’s birth date and how early they arrived to see their corrected (adjusted) age.
Enter a birth date and gestational age to see the corrected age.
Corrected (adjusted) age counts from the estimated due date, so a preemie’s development is compared fairly. It’s a gentle guide, not medical advice — your care team knows your baby best.
What’s inside
Made for the preemie journey
Corrected age, always
Growth and milestones are measured against your baby’s due date, so progress is compared fairly.
Gentle milestones
A calm, CDC-based checklist by corrected age — conversation starters, never a race.
Daily care log
Feeds, diapers, sleep, medicine, temperature and activities like tummy time — in one timeline.
Pumping & milk
A kind space for expressing: sessions, left/right, supply trend and milk-storage guidance.
Growth you can share
Track weight, length and head circumference, and export a tidy PDF for your care team.
Vaccine schedule
The CDC immunization schedule with done-tracking — and a reminder that preemies dose by actual age.
Firsts & memories
Keep the moments that matter — first night home, first cuddle, first outing.
Early support & therapies
Know what help exists — Early Intervention, PT, OT and speech — and when to reach out.
For every little one.
Whether your baby arrived weeks early or right on their due date, LittleSteps follows their growth at their own pace. The corrected-age tools are built for preemies; for full-term babies, corrected age simply equals their actual age — so everything just works.
There’s no “behind” here — only your baby’s own journey, gently kept.
