My older DS is 3 yrs 4 mos. His speech has never been an issue - he does have a bit of a lisp but no other concerns. Just the past few days, he seems to have started stuttering. He just gets hung up on a couple of words - "what", "why" and "look" at the beginning of a sentence are the ones we've noticed. "What" has become really tough for him, to the point that it takes him a while to get it out and a couple of times he's said "momma, can you say the word for me? I can't say it." I am wondering if this can be a normal stage or should we start looking into speech therapy? As I said, it has really only been going on for a few days but I want to get intervention for him if he'll need it. Thanks for any advice!
