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

What can a child 5 months:

Well hold his head and keep it straight when sitting;
Somersaults, rocking and bends;
Pulled up in his arms, trying to sit down;
Suck his toes;
Grabs, holds, feels, draws to itself, throws things;
He plays with a rattle that is nested in his hand;
Knows how to keep a bottle of one or both hands;
With pleasure to consider the person in the pictures;
Protesting and resisting an adult who is trying to take away his toy;
Distinguishes between familiar and unfamiliar people;
He likes to play during the meal;
Pronounce vowels and some consonants;
Looking around in an unfamiliar environment;
Leans to look at the fallen object.
