My 2.5 year old is talking but not asking questions except"what's this?"(and not a lot).If I ask her a question requiring a yes or no answer, she repeats it instead of answering "yes".She has a lot of echolalia&talks about herself in the 2nd person "you want water" instead of "I want water"She also has periods when she is "in the zone"-doesn't want to play much,just wants to sit on the couch and rub my hair in her face&on her hands.She loves to play with my hair,esp. when overwhelmed or tired.She makes eye contact,some days more than others- generally she will look people in the face, even strangers, and say hi & bye.Sometimes she stares off for a few seconds, not blinking. If I wave my hand in front of her face, she will "come back",sometimes it takes 2-3 seconds.Some days she's chattery &happy,other days seems to be in her own world, and even though she talks, it is mostly repeating the same things. She is always talking about what is a boy or a girl. The first thing she says when I come home is:"Mommy is a girl".She has no concept of "why" or "How".She doesn't know "mine",says "this is yours" meaning mine. Doesn't want to do things herself, will insist I dress her etc.She repeats portions of shows&movies.She likes some books,but I think she is not really listening to the story,just looking at pictures.Story hour was a complete disaster when we attempted it.I feel she understands us- "bring your shoes","use the fork"etc. It is the talking back&spontaneous sharing that we are missing.I am a first time mom & don't know how much of this is cause for concern. Please help.
