About Developmental Milestones

Developmental milestones are skills and behaviors that most children display by a certain age. Week to Week synthesizes guidance from trusted frameworks including the CDC (Centers for Disease Control and Prevention), WHO (World Health Organization), and Montessori education philosophy to help you understand your child's development and find activities that support their growth.

Remember: every child develops at their own pace. These milestones are guidelines, not strict requirements. If you have concerns about your child's development, consult with your pediatrician.
