I bought a Nap Nanny back 6 months ago, last Dec/Jan. I got it from Babys R Us--I doubt they would sell anything that was recalled the previous summer. Perhaps the previous posters are referring to something else-?
I bought it because our nanny was having difficulty putting our newborn into her crib without waking her up. We kept the nap nanny downstairs and it worked great. However, I will mention we only used it for naps (not for sleeping the whole night) and only used it in the living room (never put it in our bed). No one (as in the baby's caregiver) was sleeping while the baby was in it; she was supervised while sleeping in it. When our daughter started sitting up and rolling over (when awake or asleep), we stopped using it. It is suppose to be placed on the floor, due to any risk that the child could get loose from the straps and fall out; you shouldn't use it on an elevated surface.
I think this product is great if used in a manner that is consistent with the manufacture's intention and for *newborns*. Once the infant is more mobile, its no longer appropriate. Our nanny's daughter had a baby and she then used it; her baby had reflux issues and the elevated positioned helped with that.
