Do you think dads should bath daughters and until which age?

Personally, I think once the little girl starts school proper, it should stop -- so maybe around the age of 4-5? I've also read that it is in this age range (4-6) which a child will develop gender identification, consistency and stability i.e. she knows that she is a girl and she will grow up to be a woman etc. Around this age is also the time that many children start to have some sense of or have been taught about modesty. Plus they would have started school and would have been taught basic male/female binaries e.g. separate bathrooms etc.
