My argument has been that if my son's comfortable with me seeing him in the bath at this point in his development then it isn't an issue, and of course I would never go in to the bathroom uninvited if he was in there. My daughter was about 11 when she stopped wanting me to come into the bathroom with her, and I respected that immediately.
