My ds is about 32 months and seems to be developing something of a stammer. It is most noticeable when he is excited or keyed up. Does anyone have experience with this?
Just so you know, the politically correct term for it is "blocking," not "stammering" or "stuttering."
We found a very good speech therapist for my son who was able to help him overcome this.
I completely disagree with the PP--DON'T tell him to "take a deep breath" or "think about what he is saying." That will make him more self-conscious about it.
DO slow down your own speech. If you talk fast, he may be trying to keep up with your pace.
Also get down on eye level with him, and perhaps touch him, so he knows that he really has your attention.
If it continues beyond a few weeks, I would take him to a speech therapist if I were you.
