The posterior fontanel typically closes by the age of 2 months, so finding it open in a four-month-old infant would be considered abnormal. The anterior fontanel remains open until about 18-24 months, and good head control and the ability to roll from abdomen to back are normal developmental milestones for a four-month-old.
