Query: Unsafe Product Disappoints

I had high hopes for this positioner. I ignored earlier reviews warning about the "slide" factor. Unfortunately it is true. My baby slid down, completely off the positioner, and UNDER her blanket. Imagine finding your infant buried under a blanket. She was 4 weeks old, and thank God she was not suffocated. We have not used it since, and I cannot recommend it because I consider it unsafe.
