Yes! Each children is different. Some are more social and extroverted than others. Some like to spend time by themselves.
It depends on the environment the child grows. Kids in large families tend to be social.
If the kid doesn't like to play with other kids ,do not force him to do so. Just offer him opportunities like taking to parks or if there are kids in neighborhoods, just make friends with their parents and let the kid play.
The Kid will like playing with other kids as he grows.
Do not worry, it is a normal behavior.
