Oh he's forever playing trumpet with it! As soon as the nappy is off his hand is on it! The girls never did it much at all, but I think boys are a little more attracted to it because it's out there and they can hold it kwim? I really don't know why they would go so far as to actually call it masturbation though, because by definition they aren't doing it for sexual pleasure and at a young age I don't even think they do it because it feels *good*, it's simply them touching a different part of their body so I don't do anything about it at all - why would I? That would only create more issues by thinking it is somehow wrong for him to touch his own body.
