Mille-feuille de coton Mille-feuille de coton For newborns to around 3 years old. Snap buttons on both sides and the right shoulder make it very easy to dress even newborns. I received this as a baby shower gift. I used it for two winters only. There is some yellowing on the third photo and it shows signs of use, but it is 100% cotton, so it feels nice to the touch. From the following website: ◎ This 6-layer gauze sleeper is cool in the summer and warm in the winter, making it a comfortable material year-round. ◎ It becomes softer with each wash, and becomes fluffy by containing air. ◎ It also has the advantage of drying quickly because air passes through it. ◎ The snap buttons make it easy to put on and take off, and make it easy to change diapers and change underwear. Please purchase only if you understand the above.
