Track your baby's developmental milestones by age. See what milestones your baby should reach at each stage from newborn to toddler.
The Baby Milestones Calculator estimates your baby's developmental progress based on their birth date and compares it against CDC developmental milestone guidelines.
Here's how the calculator works:
Note: Every child develops at their own pace. These milestones represent typical age ranges â not strict deadlines. If you have concerns about your child's development, consult your pediatrician or healthcare provider.
Tracking milestones helps identify potential developmental delays early, when intervention is most effective.
Knowing what to expect at each age helps you choose the right toys, activities, and interactions to support your baby's development.
Your pediatrician uses milestone checklists at well-child visits. Being familiar with milestones helps you have informed discussions.
