✅【 Stops Baby's Rolling Over 】 This is a baby roll-over prevention belt that stops babies from rolling over. By securing the "swaddling belt" and "swaddling sheet" worn by the baby, it prevents accidents such as babies who have just started rolling over from not being able to roll back onto their backs, or from falling out of bed. ✅【 Can be put on and taken off with just a zipper 】 Once attached and secured to the swaddling sheet, it's easy to put on and take off with just a zipper. We've responded to mothers' concerns about "waking the baby with the velcro ripping sound when attaching or detaching..." ✅【 Can be used on both beds and futons 】 Can be used with baby mats with a circumference of 170cm or less, or for baby firm cotton futon mattresses.
