Skills of the month — with the date saved
Each page lists the skills babies often learn at that age. Tick off what your baby can already do and Wobbly keeps the date. Over the year it turns into a record of firsts, collected on the “Our first year” page.
Milestones at a glance
A few skills that most babies show by around these ages:
- 2 months — smiles at you, holds the head up during tummy time
- 4 months — holds the head steady, brings hands to the mouth, coos back
- 6 months — rolls from tummy to back, leans on hands when sitting, laughs
- 9 months — sits without support, looks when you call their name
- 12 months — pulls up to stand, walks holding furniture, waves bye-bye
Every baby has their own pace
Milestones are ranges, and a few weeks earlier or later is common. If your baby loses skills they used to have, or you have a feeling something is off, talk to your pediatrician — you know your baby best.
Questions parents ask
Which ages does the calendar cover?
Thirteen pages, from birth to the first birthday. Wobbly opens the page for your baby's current month automatically.
Is the development calendar free?
Yes. All months, skills and games are free.
What if my baby hasn't reached a milestone yet?
Milestones are guidelines, not deadlines. Many babies reach them a little earlier or later. If you're worried, or your baby stops doing something they could do before, talk to your pediatrician.
