This is a set of a belt and cover to prevent babies from sleeping on their stomachs. It easily attaches to mattresses and futons with a circumference of 170cm or less using Velcro, providing a sense of security to the baby like a swaddle. It folds up compactly, so you can take it with you when visiting family or traveling.
