K.G.
My son stuttered on and off for about a year when he was 3... He would do it for about 3 weeks then stop for about 2 months... I was worried also.. My pediatrician said not to worry either... His tongue isn't quick enough for his brain... He's now almost 4.5 and barely stutters.. Once in a blue moon I'll hear him (normally when he's excited) and I'll just tell him to slow down.
