Hi P.,
My son will turn 3 in 6 weeks. I consider him very bright and well adjusted. He knows hos colors, ABCs, shapes, numbers up to 29 in 3 languages.
He never says "I" or "me" but calls himself by his first name ("Merwan does it"). He does say "mine" and "my" and use these 2 equally with "Merwan's".
He does say yes, but never only yes. For example, if asked "Do you want some bread", he will answer "Yes, Merwan wants some bread. Thanks you mommy".
His conversations are lots of repeating. For example, yesterday we saw a little boy kicking his mom at the park (!). He explained to each of us at least 10 times what happened, again and again (a little boy at the park. He kicked his mom. It is wrong. It is not right. He will be punished. His mom is sad. He kicked his mom. That's not nice to kick your mom.......). I believe it's a way for him to take the story in and practice with sentences. He has something he can talk about, so he talks about it again and again.
He hates answering questions, from what color is this? to do you want an apple or a banana for a snack? But, he loves to play, so we play a lot and I know what he knows by learning. For example, we play "firefighters", meaning that he pretends he's offering me a birthday cake and the cake goes to close form the curtains and put fire on them. Then, he calls the fire station and gives our address.
O, we play with his magnet numbers on the fridge, and I say "Oh, look the 6 is on the floor" and he answers "no, that's not 6, that's 7)
I am teaching him now that if he gets lost in a public place, he shouldn't move and just call me. And if someone asks, he shall give his name. We play pretend about it, and he gives his name and address to the police officer, but in real life, I'm not sure he would do it!
Open questions (tell me about what is in this picture, about the colors of this painting...) works much better on him that "What color is this".
