When you investigate what these dolls are for, you realize that they have an important and sweet function! That your Baby feels accompanied while sleeping!!
This happens about three or four months, when they already sleep in their crib. To do this, you sleep with the blanket for three or four days and so it will be impregnated with your smell! With what your little one, when he hugs him in his crib, he will have the feeling that he is with you!
