6 month baby is not laughing...
If your worried that your child isn't hitting the milestones at a certain age your child could just be a late bloomer. As long as your baby can smile and interacts with you there shouldn't be a big concern.
How your child plays, learns, speaks, and acts offers important clues about your child’s development. Check the milestones your child has reached and talk with your child’s doctor at every visit about the milestones your child has reached and what to expect next.
