The Nap Nanny is a fairly new product designed for babies with acid reflux, colic, or congestion. It's made to be better than standard wedge because a harness keeps baby safely in place.
Many parents end up letting their baby nap in the car seat for a similar effect, but the Nap Nanny claims to have: "contours of a car seat, the comfort of a baby blanket and the stability of a mattress." It can also be used to bottle feed twins comfortably.
The Nap Nanny is a new product to us- has anyone used it?
