What do you think of sleep positioners for babies? Many of my friends swear by it to prevent flathead and correct positioning and prevent SIDS

It is recommended that sleep positioners not be used in your baby's bed. The ideal sleeping environment for a baby is a plain crib with just a fitted sheet over it. You can either swaddle your baby or use a sleep bag if you are afraid your baby will be cold. There is no need for a pillow at all. If you want to raise your baby's head, you can fold a piece of muslin cloth and place it under your baby's head. Muslin cloths are breathable and will not suffocate your baby. There is nothing on my baby's bed except a fitted cot sheet. I use a sleeping bag for her at night when it gets chilly. http://www.babycenter.com/404_is-it-safe-to-use-a-baby-sleep-positioner_10351053.bc
