Development of a child under one year - the third month

What can a child in 3 months:
He laughs out loud;
Capricious and whines, cries;
Babbles in response to sounds;
Responds to the presence of parents is trying to attract attention;
Gets his hands on the toys that hang above the bed;
He grabs a toy and pulls it into her mouth;
On the abdomen, can catch up on my elbows and shoulders and hold your head elevated for 10 seconds. Rolls from back to side;
Rests on a solid surface in feet, supported under the armpits;
Not only raises his head, but it turns out in all directions;
Finds the source of light and sound;
Expands the fists;
The child first discovers the existence of hands, then feet;
Reflexes disappear as the actions become more arbitrary;
Tightens his body when he picked up;
Explores his face, eyes, mouth with hands.
