My little girl who's 4 and the little boy next door who's 6 were playing in the garden in the play house. I was checking on them every 5 mins or so when I saw my little girl with her pants half down and when I said something they both ran out looking like they'd done something wrong although i didn't see much and they'd only been in there 5 minutes. Is this just a natural curiosity? I'll have a talk with her later.
