My son is 6 and started 1st grade a few weeks back. He his a good hearted kid but a little shy so when a new kid wanted to play with him he jumped at the chance.The boy is six and in his class, I was happy to see my son have such a good friend. Untill I noticed the little boy always has he arm around my sons neck and I saw him give my son a kiss on the cheek. It looked like my son felt unconfortable but it's his friend and I don't know if he can tell him to stop. Is it normal for a boy to do this at this age? Should I get my son into another class and tell him not to be his friend? Please help!
