My sister has a DS who will be four in a couple of months. He has always loved wearing as little as possible and if he could, would just wear pants everyday. Recently he has started asking his Mum to take her clothes off and become really interested in her bras. She wasn't worried about this and doesn't have any kind of issue with nudity and of course he has seen her naked many times. However, he asked her the other day if she ever took her clothes off in front of people or was this only in his dreams and says he often dreams about her naked. She's wondering if this is normal behaviour for his age. Any advice or comments would be really appreciated. Sparkle.
