The development of a child under one year - the ninth month

What can a child 9 months:

Claps and knocks things;
Picks up and plays two things at once;
Maybe flipping pages are thick cardboard books;
Small items take your fingers, and large two-handed;
Can not only be a good fit, but they can go to a sitting position and sit down to a prone position;
Knows how to rip and crumple the paper crumples to the palm clay;
Rhythmic jumps and crouches at the base or holding on to my mother's hand;
Self-sits, sitting, walking with support, crawls;
Can be deployed when the creeps;
Sticks fingers in all holes;
Can learn to protect themselves and their toys;
Shows the nose, mouth and other body parts mom, dolls, with myself in the mirror, sometimes getting the right finger to the right place;
Simulates different sounds;
Powered by the audience, repeating the action, if his praise;
Find a toy hidden in his eyes;
Performs a simple request.
