Milestones

Milestones are behavioral or physical checkpoints in children’s development as they grow. All of our developmental milestones are validated by American Academy of Pediatrics findings. These are the core skills all children should be reaching.

Abilities

Abilities are additional skills your child should be developing. These are important skills that 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 any milestones, be sure to talk with your healthcareprovider.

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.
