My son didn't start speaking clearly OR in sentences until shortly after his third birthday. Before that, he had very few words -- unless he was doing the echolalia thing (which was often). Now, his speech is more like that of perhaps a 2.5-year-old. He can convey his needs, narrate what's going on, or monologue about trains or diggers, but very seldom does he try to ask questions or have any kind of conversation with people. He still does a lot of echolalia. When I'm telling him bedtime stories, it's like I'm hearing myself tell it on a 2-second delay, word for word. Since I make them up as I go, it's pretty amazing to me that he can hear and repeat what I'm saying, rapid-fire, just a second or two behind me. His diction isn't the greatest, which is why he's been referred for ST, his voice is quite loud and sometimes his tone is a bit odd, and he sounds a little French sometimes because he says "de" instead of "for," For instance, he often insists he wants "oatmeal de breakfast" or that his homework letter is "J de James." As for first words, I know for sure the first was "Mama" and the second was probably either "Dada" or "car." Probably car.
