Hi Christine and thanks for your reply.I am glad to hear that others are experiencing the same.
Thanks for your reply too Misty, and like you said a lot of the stuttering is occuring when my son is tired, excited or upset. I will be keeping a close eye on how things progress.

I spoke to someone yesterday about the situation and the advice they gave me was to ignore the stuttering. I was told that some children do stutter because of the extra attention they get for doing it (because you are always correcting them, therefore they have your attention) so i was told that you are best off to ignore it completely and see how things progress.
Of course if the problem gets worse or continues then you would need to do something about it. I wasn't sure if this would be the correct way to deal with it but i have given it a go since about 3pm yesterday afternoon i can say that i have noticed a difference, nothing to drastic yet but i think over time it will continue to improve.

Anyway i will keep you informed as to how things are going.
