Hi D.,
I have 2 boys and 1 girl. I think it can go either way for Mom or Dad giving the children their baths. When the children have an "issue" then it is time to stop. My boys and I have talked openly about the difference between boys and girls and that is not appropriate for ANYONE to touch your Private Parts! Our Doctor also talks to the children about this at their visits.
The human body is something we all have in common and should be discussed openly. If there are open lines of communication your children will tell you everything you need to know about what they are feeling.
Good Luck to you and your family!
