A.D.
My 32 month old son has a speech delay (with no known medical reason) and started ECI at about 27 months. He had about 5 words he used regularly when we started and now has at least 50 (I have actually lost count!). We are still working on phrases and sentences but he jabbers constantly and his frustration level has gotten much better. I just remind my self that he will talk eventually!
One of the challenges we have is that he is very stubborn and won't imitate me, so saying "Say Ball" get's me no where. I made up some games with homemade flashcards (try www.mes-english.com/flashcards It is an ESL page with great free flashcards). I read once that boys learn better when enganged in a physical activity, so for verbs we pick a card , like jump, and then jump around the room. For objects you can hide the cards like a scavenger hunt with a treat at the end or match the object in the house ( a pic of a pillow on his pillow) and see who can get the most. Sometimes he will go weeks without saying anything new and then it will be a word bomb. Some kids have to let something new sink in for a few days. Good luck and be patient!
