Thank you for viewing. This is a Swaddle Up Lite (for spring, summer, and autumn / suitable temperature 24-27°C), size M. It suppresses the Moro reflex, and my child slept well. The effect is great! Also, the double zipper is very convenient for changing diapers. I am selling it because my child has outgrown it. I have two for washing, and I am selling both of them together this time. There are no particular stains, and it is in a clean condition. Please check the condition in the photos. Please understand that this is a used item that a child has used before purchasing. ※ The following is a reprint from a shopping site. [For spring, summer, and autumn (0.2 TOG / for 24-27°C)] 97% cotton, 3% polyurethane. Size M, for 6-8.5 kg. This is a thinner type than the original, and is also recommended for warm seasons, babies who tend to get hot, and when combined with thick underwear for autumn and winter. [Why it contains polyurethane] By including not only cotton but also polyurethane, it achieves elasticity that conforms to the baby's movements. It uses stretchy fabric that considers hip dysplasia and hip joint malformation. [Thin fabric] The fabric is not only stretchy but also breathable. Although it wraps the arms and legs, it is approved for safe use. It eliminates the need for futons and blankets, providing safer and better sleep for babies. Thank you for viewing!
