My DD who is 5 had a play date this week with a girl also 5. They play very well and had a great day. They did keep nipping to the toilet together which I thought nothing of. DD told me later that her friend asked to see her private parts and they both showed each other. She says nothing else happened and they just looked. She wasn't upset by this but she did say her friend told her to keep it a secret. I have explained to her that her private parts and hers and not to be looked at/touched etc by anyone and she must tell me if anyone ever does. My question is, is this normal inquisitive behaviour from 5 year olds or should I be making a bigger deal of this? Do I speak to other girls mum? Just want to make sure I get this right.
