A gentle reminder
Development isn’t a race
Babies often focus on one area at a time. A burst in movement can come with a quieter spell in talking, and the other way around.
Trust your instincts
You know your child best. If something is on your mind, your healthcare professional is always a good person to ask.
FAQ
Questions parents ask
Is this a milestone test?
No. It’s general information about what many babies do around each age. It can’t tell you whether your child is on track.
My baby was born early. Which age should I use?
Many professionals use corrected age for premature babies in the first couple of years. Ask your healthcare professional what’s right for your baby.
