Never had any problems with it growing up, although we were generally only naked at bath times (and seeing other people in the bath was ok)! In bed in the summer everyone slept nude, although when we went in for cuddles in a morning we put on a nightie and mum and dad would cover up.

Until maybe about 7ish I think.

I remember my aunt being freaked out I slept naked when I was about 9-10 (I had on just a dressing gown because I was about to go to bed). Until then I hadn't thought it was odd.

But I just naturally grew out of it and I assume DS will too as his body changes and his hormones make him more private.
