Stages of Development for Infants

Learn about the stages of development for infants and at what months these stages typically occur.

 

I’m Dr.  Jesse Alba. I’m a board certified pediatrician and a fellow of the American Academy of Pediatrics. I work with Alpine Pediatrics in Orem, Utah. So there’s several different stages of child development. When you go to take your new child to the pediatrician’s office, typically as a pediatrician, we’re gonna be asking you what your child is doing. At two weeks, they’re not doing very much. Typically they’re going to be maybe starting to smile just a little bit at you, but typically not gonna be interacting a lot with you. They’re pretty sleepy, they’re gonna wake up to eat and poop and sleep again and all that kind of stuff.

By two months, however, children wake up a little bit and I’ll often tell families that they can expect the child to look right at them, to respond to them,to smile at them, maybe a little bit of cooing, little oohss and aahs and goos and gahsis pretty normal to see. A question people ask me a lot is when should I be nervous about my child’s development. And that can be very difficult. There’s a lot of good resources that you could use. If you go to healthy children. org, that’s a website run by the American Academy of Pediatrics. It talks about normal developmental stages. Also, a good conversation with your pediatrician’s gonna be key.

Things that would be concerning to me,a child who is now nine months old and not rolling over at all, that would be very unusual. Typically children are rolling by four to five months of age and I’ll usually give them ’til six or seven at times,but if by nine months they’re not rolling over, that’s concerning. By 15 months of age, if they’re not walking yet,that’s typically very concerning as well. And it may be a normal developmental delay for them but it may be a sign of something else going on. Language development is a really important one to watch and that starts slow.

By nine months, your child’s babbling, starting to make some mama dada sounds. By one, one to three words. At 15 months, four to five words. At 18 months, eight to 10 words. So if I have an 18 monther come in who’s not even saying mama dada, that’s pretty concerning to me. Typically, I’m gonna look for that by about 15 months of age, hopefully much sooner.

If you have concerns about your child’s development,the best thing you can do is get him into your pediatrician, have a full evaluation done, talk about it,see how they’re doing. It’s very easy to compare your child to other children that you may know and a lot of parents get worried about that. If all their cousins are walking and they’re 10 months old but theirs is not walking yet and their 13 months,that may be developmentally appropriate for that child. The best thing you can do is get in and chat with your pediatrician.
