Please don't judge me too harshly on this, I've searched the internet and can't find anything similar so have joined purely to ask!
So we go regularly swimming with a little girl and DS (both nearly 3) adores her and afterwards we all get changed in the only family changing room at the pool. There's usually some pretty standard boy behaviour of "look at my willy!" and piddling contests... as you do. I accept this as normal.
However today he started playing with it and then exclaimed that "he'd made it big" (embarrassing enough in front of a mum of a girl who was unaware that little boys that young could actually get an erection, everyone was very red faced) and proceeded to cuddle his friend, so we chose to ignore the erection until he started pushing it against her and rubbing it on her!!
Of course I pulled him away and freaked, I was mortified! Very quickly got him dressed and hoped the ground would swallow me up making excuses that I have no idea where he got that from and it's not sort of thing he's ever seen to copy! It's not like I could ignore it when there was another child involved - he's usually playing with it and I've given up telling him not to and gone for the whole "only when you're on your own" / "why don't you go somewhere quiet to do that" chat instead.
He's never walked in on me and DH (on our annual night of passion!) seen anything inappropriate on the TV and our dog is a girl so it's not like he's seen her hump anything... where the f* has he got this from and is it something that he's likely to do again? I've seen some threads about boys humping furniture and stuff... but another child?!
I really don't want to damage my relationship with this friend as the children play so nicely together. Certainly won't be getting changed together in future!
Helppp!
