#asktheexpert Hello doctor, my baby was prematured. Now his birth age is 3 month. He was born at 33 weeks. He doesn't make a social smile yet. Is there any problem or I have to wait till his adjusted age of 2 month?

A. If she was born at 36 weeks gestation, she will not smile until about 12 weeks of age rather than 8 weeks. This holds true for all developmental milestones until about 2 years of age when most premature babies have caught up with their peers.
