I honestly would not worry to much about right now.
Boys usually decelope slower than
girls. Often they learn to speak, walk, and potty train later than girls. But, if you notice as he gets older he is still having problems you might want to have him evaluated by a pediatric doctor. My nephew also had these problems and it turned out he had a mild form of autism. I don't want to worry you at all, in most cases like I said before boys just mature slower than girls.
