Ma Petite Laine was born in 2019, when Agathe, a physiotherapist specializing in infants, introduced Olivia, her neighbor and no less friend, to her first cocoon... Agathe had knitted a large sock with her little hands, for the arrival of her third daughter, Lucie. At the maternity ward, the nursery nurses were fans of her, of course Lucie, but above all of her large woolen sock, in which she found the permanent contact and the flexed position so much appreciated by newborns. It was like a click, we both had to make new mothers and childcare professionals discover the benefits of this miraculous ""sock"" which was renamed cocoon :-), as well as the virtues of merino wool .
