Esmeralda Donut Pillow Hello Pattern Baby Pillow I used this for about 3 months with a gauze sheet. Although it's difficult to see in the photos, there are stains on the collar area, etc., if you look closely. I think it would be fine if you use a towel or something similar on top of it＾＾ The fluffiness is still somewhat there, but I think it will recover a bit more with washing.*
