As they say, no matter how the child is amused, if only it would not cry. And, as a rule, desperate mothers and dads stick a dummy for the child every time they cannot reassure it. Kids are born with an innate sucking reflex, in the womb of his mother he sucks a finger or plays with the umbilical cord. Appearing on this light, he still does not know how to do anything, but if he offers him a chest, then he will immediately suck on the smell of milk. Nature arranged so that children are not only saturated, but also soothe themselves.
