Query: Wonderful

I bought this when my son was a few weeks old hoping it would help with his congestion. It did help and he really likes the side wedges that make him feel enclosed. He, like others mentioned, would skirm down into a ball. But, if you positioned the wedge to one end of the crib so that his feet could touch the bumper pad, I found that he would push himself back up. He is now four months old and goes right to sleep when I put him in the wedge. On average he sleeps 12 hours a night. I will definitely keep using.
