ds1 (3) was told off by a very angry grandad when he came to stay with us a week ago, and I'm taking the kids to stay with the grandparents next week. He told him off 3 times, for pushing him and for pestering the adults when we sat down to have a cuppa. My dad is a very large man and physically strong (he grabs ds a lot and physically gets him to do something, I've seen a bruise once) and of course ds was reduced to tears and I had to spend half an hour consoling him. My mum says don't leave ds on his own with grandad. Its all a bit worrying, anyone else had this to deal with?
