Doctors use milestones to tell if a baby is developing as expected. There's a wide range of what's considered normal, so some children may gain skills earlier or later than others. Babies who were born prematurely may reach milestones later. Always talk with your doctor about your baby's progress.
Here are things babies usually do by this age:
Communication and Language Skills
take turns making sounds with you
make squealing noises
Movement and Physical Development
roll from tummy to back
push up with straight arms when on their tummy
lean on their hand to sit with support
Social and Emotional Development
know familiar people
enjoy looking in a mirror
Cognitive Skills (Thinking and Learning)
put things in their mouth to explore
reach to grab a toy
close their lips to show they don’t want more food
When Should I Call the Doctor?
You know your baby best. Share your concerns — even little ones — with your baby's doctor.
If your baby is not meeting one or more milestones or you notice that your baby had skills but has lost them, tell the doctor.
