Crescent Womb was designed to comfortably support your child as if being held. This reduces tears, and improves sleep for baby AND parent. The mesh sleep surface helps baby self-soothe while increasing breathability and reducing the risk of over-heating and suffocation. It's a winning combination.
Also, Crescent Womb is extremely versatile. Portable, machine washable, and able to attached to just about any crib or pack n play so you can use it anywhere.
