My DD is 2.8 and has always been a dribbler but at the moment is soaking through clothes at an alarming rate, I think its possibly the worst it has ever been. I'm pretty sure she has got all of her teeth, the back four have just about come through so don't think it's that. She has speech and language therapy but we had to cancel a session so I can't ask her till end of June. Any ideas on what causes it, is it a problem (other than frequent washing!)?
