Sleep Positioners have been advertised as a way to reduce reflux symptoms and prevent flat heads from back sleeping, but they have never been proven to help in any way. Unfortunately, now we have data that actually shows them to be unsafe. The Consumer Product Safety Commission have officially asked families to discontinue their use due to a suffocation risk. Please stop using a positioner if you are using one, tell your friends and family and never buy this as a shower gift!!!
