Kell, I had a similar thig happen to my daughter years ago. I rang the parent whos son was being very unkind to my daughter. I felt terrible that I had to ring but was glad I did. The Mum thanked me for contacting her and was greatful that it could be dealt with before it got worse. After speaking with the mother he was made to write a letter saying he was sorry. It cleared the air and things improved. Let your son know you still love him but not what he has done. We all wish our child/ren were perfect but thats not the real world. Keep up the good work of parenting and all the best with the new arrival.
