Milestones

Milestones are scientifically supported behavioral or physical checkpoints seen in infants and children as they grow and develop. All of our developmental milestones are validated by American Academy of Pediatrics findings.

Abilities

Abilities are additional skills your child should be developing. When reviewing abilities, look at your child’s overall behavior to gauge their progress.

It’s Important to Remember:

Be sure to adjust for prematurity.  If your child is missing milestones, be sure to talk with your healthcare provider.

Missing one or two abilities should not cause alarm, as every child develops differently. However, if they are missing multiple abilities, be sure to talk with your healthcare provider.

Use our checklists to track your baby’s development and discuss any concerns with your healthcare provider.
