We are having a bit of an issue with my 3 year old, he is petrified to the point of shaking and screaming when he sees his nanna and grandad (my partners mum and her husband). It is getting out of control, if we go to visit them we cannot get him out of the car without him breaking down and he will not leave our arms once we do get inside the house. His most recent episode at his 3rd birthday at a local park having a ball until he saw them and he lost it, screamed wanted to leave and shaking. Does anyone else have any tips on what this could be, he does not have this issue with anybody else it is purely these 2 people. I'm to the point I don't want to take him there to see them anymore because he is terrified and it doesn't seem fair to put him through it!
