I think the SnuggleU is a non-negotiable infant baby product, and i have tried an embarrassingly large number of baby products! As an RN, I am all about the Back-To-Sleep campaign (in effort of SIDS reduction/prevention), but it seems most infants dont sleep well in a bare crib with nothing around them. I feel the SnuggleU is the product to bridge that gap safely, as it provides a snug and secure feel to any safe, flat sleeping surface (crib, packnplay, travel bed, etc.).
As the winter approaches, I also added a Kiddopotamus Snuzzler Complete Head and Body Support (cheap on ebay!), which provides lots of warmth and further support (but I wouldn't use this for a more mobile, rolling over babe!)
My daughter was in the NICU as a preemie and the nurses used a similar product there as well. Plus Val has managed to make the covers a fashion statement and I hope there is a sale on more covers sometime! Would recommend this product to anyone with an infant. My daughter is just shy of 3 months old and she is still using it!
