My son was speaking very clearly and would repeat everything you said to him without any problems. My godson studders and is 5yrs and so is my daughter she doesn't studder. They were playing last sunday the next day my son is studdering. I thought it might have been him hearing his godbrother doing it but it's going on 10 days of him doing it now.

Since yesterday i'm noticing he's getting so frustrated trying get the sentence out that he won't even try to finish saying it at all. Help should i be concerned or is it a phase.
My son's dad says he caught the kids tickling him and that caused it. that just sounds bogus.

My brother in-law says something had to have happen to him like what?
