my baby is 10 week old, he is not smiling by looking atbfacr, is it ok

A. hello it is normal and nothing to worry about.. As with all things in child development, there's a range of normal when it comes to when babies smile. But if your baby doesn't show a social smile by around 3 months old, talk to your child's doctor. This could be an early sign of a developmental delay that may need attention
