The American Academy of Pediatrics’ website, healthychildren.org, has a comprehensive list of developmental milestones for select months. For convenience, I am including links through 1 year of age. These are based on birthdates. If your baby was born prematurely, then you will need to calculate your baby’s ‘adjusted age’ and find the corresponding milestone for your baby. Remember, if you have any concerns, please contact your pediatrician!
