had a boy to play yesterday who was telling me - not for the first time - that he doesn't think his dad loves him because he is always shouting at him. The boy is not a sporty type, has a younger brother who is, dad finds it easier to relate to the younger brother as he likes sport.
Naturally I've reassured him that his Dad does love him and said things like sometimes we love our kids but don't like their behaviour at that time. Also that more is expected of older children.
Would you have a quiet word with the mother? I don't know them very well and I'd possibly have to phone as I don't usually see them without the child there.
