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

'The No.1 mistake is that parents think that if they sell it, it must be safe. That's not true. Seep positioners are infact dangerous for baby and should be avoided U.S GOVERNMENT ADVICE TO PARENTS STOP using infant positioning products - they are dangerous and unnecessary NEVER put sleep positioners under the baby or in the crib ALWAYS place a baby on their back at nap time
