YUUNYSLEEP, YUUNYSLEEP I'm selling this because I've been using it for a few months, but my child has started sleeping in an adult bed. It comes with a cooling cover. It can prevent the baby from waking up due to rolling over, and the contact-cooling cover seems comfortable for the baby. This cover is quite thick and sturdy, so it's taut overall, and I didn't have to worry about it being so fluffy that it would bury the baby's mouth and obstruct breathing. The cover has been home-cleaned. Please note that there is no dedicated storage bag or instruction manual. Please note that I will remove the cover and roll it up for shipping.
