I don't mean to confuse the issue more, but I may seek out a speech pathologist. As a nurse, I have a bit of a problem with all of the previous advice. First of all, the potential of hypo or hyperglycemia manifesting itself as stuttering is extremely unlikely. Secondly, all candida is, is a yeast infection. Pure and simple. It's very common. You may want to ask your ped about the speech pathology route or, if he/she is unwilling, see if your insurance will cover a visit without a referral. They will do an assessment and you can go from there. I know people are well intentioned with their postings, but I, at times, cringe at some of the recommendations. Sorry if anyone thinks this is too harsh.
