Thank you for viewing! This item is a six-layer gauze type, gentle on the skin, and can be used in any season! It was very useful for children who move around a lot in their sleep. I am selling it because my child has outgrown it. It can be used from newborns to around 3 years old, so I think it can be used for a long time. It can be completely separated, making it very easy to put on and take off! You can put it on your sleeping child without waking them up. This is a set of two baby sleep sacks: one with a multi-colored mushroom pattern and the other with a light-colored giraffe pattern. - Design: Mushroom pattern - Color: Multicolor - Design: Giraffe pattern - Color: Light color Please consider purchasing only if you understand that this item has been stored at home.
