- In Kenya, mothers carry their infants on their backs, strapped in a long piece of cloth, for almost 2 years. They do not know the stroller. One takes seed: one alternates portage in scarf or in kangaroo and exit on 4 wheels. It is voluptuous to be nestled against each other and babies wearing much weep less. Besides, it leaves our hands free.

- In Argentina, little ones go to bed (very late). They accompany the parents in their fiestas, and when they fall asleep, they sleep without worry in the arms of an adult, in a basket or extend on two close chairs. Seeds are taken from it; an exception is made from time to time to the regularity of bedtime. To take him when you go out at night to a restaurant or to friends is to enjoy our free time with him and to integrate him into our social life: shared happiness. The whole thing is that it catches up with the lack of sleep.

- In China, babies begin learning about cleanliness around 6 months-1 year. They wear slit pants allowing to pee directly on the ground, or held over a receptacle by the mother who creates a reflex by imitating the noise (psssiiitttt)! We take some seed: we try, from 18-20 months, to remove the layer to let it wander in panties summer, garden or tiled floor. So he feels better what happens in his body, understands where the pee comes from and can learn to ... predict.
