Just to clarify, I would not have been weirded out had the stroking just been on the face, head, back, arms etc - it was the fact that it was ALL over a child's body, pulling up night clothes, over inner thigh, chest area etc
I have to say, OP, I've been surprised that everyone thought that the stroking of the areas you mentioned was ok. My children always loved the stroking thing - but, in common with most posters' stories here, it was confined to the back, shoulders and head areas as they got older.
I do think it's quite unusual to be stroking a 10 year old child on the tummy, chest etc. Many 10 year old girls will have budding breasts - is the father going to announce one day that he can't do it any more? Far better to have a natural, gradual acceptance that some parts of the body are more "private" than others.
As a family we are very cuddly, and my children would ask me to massage their heads/shoulders even when they were in their teens, but there are natural cut-off times for certain kinds of touch. I'd blow rasberries on my babies' or toddlers' tummies, but not my 10 year olds', for example.
