Bath sharing with kiddies: Opinions plz!

I assume you mean opposite sex? I don't see any problem with parents and children of the same sex bathing/dressing/sharing a bed on vacation indefinitely.
 
I don't really see the problem, nudity doesn't equal sexual. As long as your child and you are both comfortable and happy... :shrug: I think it's fine. I think showing an example of not being concerned or making a really big deal about the way your body looks naked is probably a good example to set a child.
 
I don't think nudity in itself is a problem, but bath tubs can get quite crammed with 2 people in it, even if one is a "little one". I would feel awkward. Also, the thought of what little ones can do to the bath water makes it a definite non-option for me.
