Co-sleeping is one of the sweetest, most convenient approaches to sleep during the early months (or years) of a baby’s life, especially when Mom is breastfeeding. And although "overlying," or rolling over on a baby, is extremely rare (and is usually related to drinking or drug use in the parents), the Snuggle Nest is a nifty little resource for parents who want a little added security while bonding with their infant. Fitting between the pillows of the adult bed, the nest consists of three sturdy walls to help protect infants from suffocation from pillows and entrapment between the mattress and headboard. A firm mattress provides a safe sleeping surface, and a removable, washable envelope sheet also decreases risks of suffocation from loose sheeting. The open end allows easy access for touching, soothing, and nursing baby. This translates to less crying for baby and more sleep for Mom and Dad! The Snuggle Nest also includes a movable light and breathable mesh-covered sleep positioners to keep baby snug and in place. Traveling? Fold it up and away you go! Two AAA batteries required (not included). Discontinue use when baby can roll over or push up on hands and knees. --Emilie Coulter
