Developmental Milestones

Every child is different. Milestones provide a way to track development so that delays can be promptly identified and quickly corrected. Late identification of difficulties can cause frustration or impact your child’s self-esteem and relationships with others. 

Sometimes a later developing milestone can be attended to at home with great ideas from a Physical, Occupational, Speech- Language, or Feeding therapist through free professional consultation. If reviewing the milestones raises questions for you, we are here to help!
