What physical developmental milestones should I see at each age?

While each child is different and will learn new skills at their own pace, these are the CDC developmental milestones most pediatricians will be using to evaluate your little one at checkups. It’s important to note that development is not linear and some children will skip steps or learn and grow differently! These developmental milestones are just to help give you a sense of where your child may be in their developmental journey. If you observe that your child doesn’t seem to be meeting a majority of these milestones, absolutely raise your concerns with your child’s pediatrician so you can talk through it together! Visit the CDC’s website for more information on early screening:

It’s normal to have concerns about your baby’s development, but every baby develops at a different pace and “developmental milestones” are not universal. However, if you feel like your baby is not exhibiting more than a few of these skills at the given age range, you can bring up any concerns with your pediatrician.
