Happiest baby requires you use their sleep sack in the snoo product. The sleep sack is very constricting on the babies legs and hips and is not hip healthy. They recently updated their sack to be wider in the hips and solve this problem but refuse to refund or exchange any old sleep sacks. They also never announced this change and are being very deceptive to their customers.
