My son turned 2 in August. He has been speaking very well since the age of 1. He has a larges vocabulary, and uses sentences and his grammar skills at a level higher than his peers. He has always developed more quickly than the other children we know at his age. But recently about a month ago he has began to stutter. I consider the stuttering to be pretty bad, but he doesnt stutter all of the time. Mainly with "w" words and I. EX. He will say " wh.. wh...wh..wh..where where where are we going?" Is this something that I should be concerned about, or is this a normal childhood thing???
