Is it okay for my baby to sleep on her tummy for naps?
I was always afraid of SIDS Sudden infant death syndrome that’s why I never let my baby to sleep on his little tummy. Now Babycenter’s pediatric sleep expert tells us what’s the best way to have a nap:
Is it okay for my baby to sleep on her tummy for naps in daycare if she sleeps on her back at night?
No, to greatly reduce the risk of SIDS, you should always place your baby to sleep on her back — whether it’s for an afternoon nap or in the middle of the night, and whether she’s at daycare, at Grandma’s, or at home. In fact, babies who usually sleep on their back but are placed on their stomach occasionally (during a nap, for example) are at especially high risk for SIDS. So make sure that everyone who puts your baby down to sleep knows that she should be placed on her back.
A side-sleeping position used to be considered an acceptable alternative for babies who don’t like sleeping on their back, but the American Academy of Pediatrics (AAP) no longer recommends it as a safe option. It may be tempting to place your baby on her tummy or side if she finds it soothing and she’s fussing, but the increased risk of SIDS is not worth it, especially in the first six months of life. The peak age for SIDS is between 2 and 4 months, and 90 percent of SIDS cases are in infants under 6 months of age.
