How To Know If Your Baby Is Developing In a Healthy Way


If you’re a first-time parent, you’ve probably got lots of questions, and at Westchester Health Pediatrics, we’re ready with lots of answers. One of the most common questions we hear from our new parents is, “Is my baby developing normally?”

While there are wide variations of what is considered “normal,” we like to pass along to our parents these helpful guidelines from the American Academy of Pediatrics which describe what to expect and what to look for as your newborn progresses through his/her first year of life.

Remember, every child progresses differently

Certainly, every baby develops at their own pace but typically, by the end of the first month, a newborn should be becoming more alert and responsive. Gradually your baby should begin moving his/her body more smoothly and with much greater coordination, listening when you speak, watching you as you hold him/her, and starting to move his/her own body to respond to you or attract your attention.

Physical developmental delays, or early motor delays, are terms used to describe when children are not meeting critical physical milestones in the first months and years of life. These delays can be a sign of something more serious going on, so it is important to talk with your child’s pediatrician if you have concerns.
