ds has just turned 4 and is still dribbling quite a bit. he speaks fairly clearly, though has a bit of difficulty with s. Just wondering whether to go to speech therapy drop in or whether there is a medical reason such as large tonsils (which he has) - health visitor has always said it will sort itself out but i'm anxious as he starts school this year and i don't want it to affect him socially. does anyone else have experience of this?
