I know for LOs, exploring their bodies is a natural thing, but when is it too much? Also, how do you handle it? DD is always sticking her hands into her privates during diaper changes, and I usually let her go for a few moments before saying it's time to put her diaper on. Yesterday, though, she was asked where her belly was, and she pulled her shirt up, and after that she just kept wanting to walk around and stick her hands down her diaper with her shirt up. I know you're not supposed to make a big deal about it, and re-direct the attention, etc, but it wasn't working yesterday, and I finally had to physically stop her and tell her firmly "NO". How do/did you handle these situations?
ETA: Asking for public situations, we were at family's house when she was doing this yesterday.
