Childhood Milestones: What Parents Should Know

As parents, it can sometimes be hard to know if your child is developing at the pace they should be. Every child grows in their own unique way, but there are key developmental milestones that provide helpful guidance. These milestones can help you determine if your child might benefit from extra support, such as early intervention services.

Below is a quick, age-based list of common milestones. If your child is missing several of these, or if you’re concerned about their progress, it may be time to reach out for an evaluation.
