My daughter has had trouble with her "tummy time" since day one. She always cries whenever I try to put her on her tummy. I thought that if I could make it fun for her, that she might begin to enjoy herself. I received this product, and from her first try until her 10th try she absolutely hated it. She kept reaching down and grabbing at the mat, this prevented her from using her hands to push herself around in a circle. I think that laying on that swivel hurt her stomach, too. I gave it away just a couple weeks after receiving it. It didn't work for my daughter, but it might work for someone else's.
