Your baby's developmental milestones at 9 months
Everything you need to know about your growing 9-month-old.
By 9 months, your baby is much more mobile and likes to explore. Babies at this age are crawling and can raise themselves to stand, so safety in the home becomes an important issue as your baby's curiosity (and mobility) grows. Your baby now responds to their name, loves to cuddle with family members and may show shyness or fear of strangers. Games like peek-a-boo and pat-a-cake are sure to be a big hit with your 9-month-old.
