We went from 5-7 hrs of sleep and short wakes in between to 11-13 hrs of sleep without a peep! Wish we had found Crescent Womb earlier. This is now my go-to baby gift for all new parents. Please beware of the knock-offs out there. It's not worth a few bucks to risk the safety of your beloved infant. Can't wait to get any and all future products from Crescent Womb.
