SPEECH: He has not started talking yet. Not lot of sounds only sometimes baba
For example, if he wants milk, he will take me to the fridge, take my hand and put it on the handle of the fridge and make some sounds. When I open the fridge he tries to bring the milk can out.
If he wants me to read a book, he brings the book to me and keeps it in front of me, turns the pages and makes sounds as if requesting me to read.

RECEPTIVE LANGUAGE: He can generally not respond to one-step directions. For example, if I ask him to go to the bathroom to take bath, he will not run towards the bathroom, he will not brings his pants, shirt, shoes to me.But if he sees that his mother is dressed up to go outside he will start pushing and crying to go out as early as possible.
