Teddy cannot talk yet. He starts crying as soon as his mom leaves him on his chair and he cannot sleep. He also starts crying at many other occasions. However, amazingly, when her mom starts talking with others, he never cries. He doesn't necessarily listen attentively, but definitely he is quiet. He can maybe say some syllables on his own.
Also, babies seem to use crying to signal his/her dissatisfaction whenever s/he feels it. Since they cannot tell you something is wrong, they cry. But it's not a painful cry, because as soon as you attend to his needs, he stops.
Taking care of a baby is a tremendous task!
