My DD is 22 m.o and she has started the habit of sticking her hand down the front of her nappy and sticking a finger 'down there'. I know that its normal for little boys to play with themselves but girls?? She sometimes does it when im changing her nappy too. She doesn't stick her finger in her vagina she just grabs near the top near where the clitoris area is. Is this normal or should i be worried?? When she does it i tell her to get her hand out or it move her hand. Should i be doing this or should i just ignore her?
