This was very helpful for placing on the baby bed mattress or on the sofa, and when holding the baby with this in between, it was a great help in preventing spit-up when putting the baby down and for back-switch issues. I don't see any noticeable stains, but there may be some small ones I've missed. Made of durable and soft fabric, it can still be used. Space pattern, dinosaur pattern cover An animal-pattern swaddle is also included. [No more difficult bedtime! For back-switch measures] Babies' backs are very sensitive. They can feel even slight changes, so they wake up the moment they are moved to the futon. Kerata's baby hug futon allows you to put your baby to sleep smoothly without triggering the "back switch." [You can feel safe with the scent of Mom and yourself] [Easy baton touch from Mom to Dad!] [Appropriate thickness] Not too thick, so it's easy to hold the baby, and it doesn't sink in too much, preventing accidents like suffocation. You can put the baby to sleep with the hug futon and then place it on the futon as is. [The main body can also be washed! Keep it clean at all times because you use it every day.] [Easy to carry] [Can be used all season with Ibul gauze] Uses 4-layer gauze Ibul fabric. It contains a lot of air, so it has high breathability, absorbency, and quick-drying properties, making it cool in the summer and warm in the winter, so you can use it comfortably in any season.
