Developmental Milestones
Age-by-age milestones, tracking tools, and guidance for supporting your child's growth.
Developmental Milestones
Understanding what to expect at each stage of your child's growth helps you celebrate their progress, support their learning, and identify areas where they might benefit from extra help. BrightRoots provides families with comprehensive milestone guides aligned with nationally recognized standards from the CDC and the American Academy of Pediatrics.
How to Use This Guide
Every child develops at their own pace, and there is a wide range of what is considered typical. These milestones represent skills that most children achieve by a certain age. Use this guide as a general roadmap rather than a rigid checklist. If your child has not reached a milestone within the expected window, it does not necessarily mean there is a problem, but it may be worth discussing with your pediatrician or scheduling a free developmental screening at BrightRoots.

When to Seek Help
Trust your instincts. You know your child best. Consider reaching out to your pediatrician or scheduling a free BrightRoots developmental screening if your child:
- Is not meeting multiple milestones for their age range
- Has lost skills they previously had (regression)
- Does not respond to sounds or their name
- Does not make eye contact or show interest in other people
- Has significant difficulty with feeding, sleeping, or self-soothing
- Shows extreme or persistent behavioral concerns
Early intervention is most effective when it begins during the earliest years of life. BrightRoots offers free developmental screenings on the first Wednesday of every month, and our child development specialists are available for consultations at any time.
