We began to really notice this when he began preschool at age 4. The teachers gave us some informative papers on stuttering and said they mentioned him to the speech pathologist.
It wasn't that he was a traditional stutterer. He didn't repeat syllables or get stuck on a word or sound. Instead he would repeat phrases over and over like he couldn't get the whole sentence out. Like he might say:
"Today, today I, today I went, today I went to the store."
We weren't too worried, and the preschool teachers didn't seem too worried either. They said that it was common for preschoolers to start stuttering because they are taking in so much information and learning so fast that there is just so much in their heads and it gets jumbled when it tries to come out by speaking.
So, I didn't worry, and we continued to work with MJ at home as far as stretching his heel chords, and we already knew what foods we could get him to eat.
