Yeah, no worries with nudity here The girls shower with either DH or I on a pretty regular basis and they just think it's funny to point and laugh at announce that they can see boobies or doodles or bums lol I often saw my parents naked growing up, it was just never an issue. Except when I would have friends sleep over and Dad would be sitting on the couch the next morning in just his boxers with bits on show (okay, so that happened once and he learned to put pants on before venturing out when my gf's were over lol) or I'd come home with a friend and Mum would be lounging around in just a baggy shirt and her undies lol!! Growing up, our bathroom was tiny so we would always do the dash from bathroom to bedroom wrapped in a towel to get dressed, same goes here. The kids are always in the toilet with us (and sorry for the TMI, but DD1 has already received basic education concerning AF as she's seen my pad at that time of the month and freaked out - 'I'll get you a Band-Aid, Mummy!') when we go and I've stopped sleeping naked since the day mum dropped DD1 back from a sleepover and DD1 yanked the blankets off me... poor mum hahaha
We'll stop showering etc with the kids when they express distaste for it, until then we have no worries with naked bodies as we know they exist and there's nothing wrong with them, they just get a bit awkward when you get to a certain stage of development lol!
