▼ White Bear Swaddle S size Cotton material Brand: Coperta Sleeves open type ▼ Gray striped swaddle M size Cotton material Brand: Love to Dream No sleeves open Used for one child, then washed and stored. There are no noticeable stains, but please refrain from purchasing if you are concerned. My child seemed to get along well with these swaddles, and hardly cried at night from 2 months old! I think they work well for some children. Since it's a set of 2 sizes, I hope you can use them as your child grows. I hope that your challenging childcare will become a little easier.
