Hi there,
My DS is five, and speech-wise he's really articulate. However, inbetween some words he has a habit of sucking back his spit. It's a real "sooooooook" noise iyswim, and is become more and more noticeable.
DP and I are trying to work out how we can get him to stop this habit, without making it into a huge issue that will torment him and end up with him seeing a psych for it in his adult life! 
Has anyone any advice on how to stop a habit in a strong-willed five year old?
Thanks in advance. x
