Developmental Milestones for your Child's First 5 Years

Each child has his or her own unique strengths and talents, as well as skills that may take them a little longer to tackle. Some challenges are part of natural growth and happen at their own pace. Others may be indicators of autism spectrum disorder (ASD) or other developmental delays.


As a parent, it’s difficult to understand which behaviors and challenges are typical and which need more attention. To lighten the questions, we prepared a child development checklist. This list of expected milestones for babies through 5-year-olds does not serve as a test for autism or disability. Rather, it should function as a guide of skills in which to observe.

The American Academy of Pediatrics recommends physician surveillance during every well visit and developmental screenings for children at 9, 18 and 24 or 30 months of age. Evidence shows the earlier development is assessed, the greater the chance a child has to reach his or her true potential. So, if you are concerned about any aspect of your child’s development – listed here or not – we urge you to discuss it with the pediatrician or contact us at Hopebridge to schedule a formal diagnostic evaluation.
