Hi M.,
Hang in there.. i'm sure this just a phase.. (hoping nothing has happened with the 8 year old..) I have 3 girls; 4, 5, and 7. All of them, since birth have seen my husband and I with no clothes on.. showering togehter.. (not so much anymore now..) but suddenly their fascinated with bums.. and they giggle when they happen to see or find our underwear! I even caught my 7 year-old taking pics of her friends bum! We were horrified of course and had two serious discussions already about the inappropriateness of it.. Hopefully she's got it now.. but they love to shake their 'booties' so to speak, when they dance.. Not sure where they get this, as they really only watched PBS and very few kid movies.. There must be something innate about it all.. I think once they learn what 'private' means.. they become slightly fascinated by it.. I've even been more hesitant to leave them in the tub together as i've found them checking out eachother's bums while playing.. etc.. I'm not exactly sure where that fine line is between natural curiosity and inappropriateness.. i'll look forward to reading other responses.. and maybe gain some insight along with you..
Good Luck.. and it sounds like you're doing all you can.. keep it up, and i'm sure this phase will pass..
