The little ones are full of energy and happiness, especially when they are loved.
Children perceive the world around them, they recognize love and it is a source of stimulation, which helps them throughout their lives.
It is true that as with adults, each baby has a staff that is still building, some more cheerful than others or more serious.
But if our son was too quiet, serious or even angry, it would be a warning to think that she makes him feel so uncomfortable.
It is important that parents care about meeting the needs of their children, not in order to raise them badly, but in order that they grow up with an untamed joy, there is no better time to be happy, than the first years of life.
