I've spent ages trying to think of the right title for this so I don't sound too weird 
Anyway, I'd always heard all the jokey stories about young boys playing with themselves but I'd never heard anything about young girls doing it too. However DD, whose 3 and just out of nappies, seems to have developed a recent habit of playing with herself but also with trying to see what might fit there - bathtime is the big offender, I turned my back for a few seconds the other day only to turn back and find that she was 'playing' with the handle of a toy brush!
I'm wouldn't worry overly but she has actually managed to make herself quite sore by accident. I've not made a fuss and just explained that it's a place that is easy to hurt so she shouldn't try putting things there. That's not particularly seemed to work though. I guess she's just very curious at the moment...
I suppose I'm just wondering, is this normal development, but people just don't joke about it in the same way as they do with boys? Any tips on how to encourage her not to do it, but without making an issue of it?
(I know this does sound a bit weird and there have been a few threads like this jumped on recently, sorry, it's just something that has thrown me a bit)
