Great idea, but we never used it.
I get the idea of this product, and I'm sure many people use it with much success, but it just didn't work for us. Our son obviously didn't need it when he was a newborn. There was no way that he would be able to roll over. Once he began rolling at all, he didn't want anything to do with this. We did try putting him in it when he was a newborn just so we could try to position him a certain way. It never really worked at keeping him in one position and I always worried about him moving down in it and getting suffocated by the sides of it. A really nice feature about this one is that it has the vents to make it "cool flow". One of my biggest worries was of overheating our child at night. This can increase the risk of SIDS, so I always worried about it. The feature this has to keep babies cooler is a definite must if you're going to use a sleep positioner. Overall, I've heard this working for others and it is a well made product; however, it just wasn't for us.
