According to the American Academy of Pediatrics, the time between the ages of 4 and 5 marks your child’s transition from being toddler to a preschooler. While his physical growth and motor skills might still be slow to development, you can expect to see some great intellectual, social and emotional changes.
Below are lists developmental milestones – things that most children can do at these ages – as well as signs of possible developmental delays at this age according to the Centers for Disease Control and Prevention.

What if I notice a delay?

If you are concerned about any developmental delays your child may be experiencing, ask your child’s doctor or nurse, or talk with someone in your community who is familiar with services for young children in your area.

How important are regular screenings?

The checklists you find here are not a substitute for standardized, validated developmental screening tools such as those on this list that might be administered by your child’s doctor.
The American Academy of Pediatrics recommends that children be screened for general development using standardized, validated tools at 9, 18, and 24 or 30 months and for autism at 18 and 24 months or whenever a parent or provider has a concern. Ask your child’s doctor about his or her developmental screening.
