Editor's note: This story is part of our three-part Special Families series about families with special needs children.
Most parents feel their baby is changing and developing new skills almost daily. Parents should be mindful of the many developmental milestones and take note if babies aren't hitting these goals within the recommended time period.
Sloan Todd of Path Finders Team Services in Charleston said it's important for parents to remember that each child is different. They should use checklists as a guide and not overly stress if their child is slightly off schedule.
Parents with concerns can consult their pediatrician or contact BabyNet, the state's early intervention system for children younger than age 3.
