My son is not making any friends

Sometimes when a family separates children feel they are to blame and that they are unlikeable and that is why one parent has left the home.  Reassure him that it is not his fault and that both of you still love him.  Encourage him to invite a friend home, or if he is uncomfortable with that, you could ask a school friend to come to the park with you.  Talk to his teacher, a class is a big place and the teacher might be able to have your child work with someone who he can get on with.  Talk to other mums at the school gates, if he sees you socialising, he may join in.  Try not to let your son know you are anxious about it, so he doesn’t feel he is disappointing you.  Tell him about his positive attributes and let him know that you think he is a great.

There is some useful information on the Kidscape website that you could discuss with your son.
