Our favorite life saving sleep swaddle. 100% cotton. Washer/dryer safe.
0.5 TOG. Breathable but cozy.
TIP: When the baby is in a swing or carseat and cannot be swaddle place the blanket on top of belly area. I did this with mine so that I could feed the other baby. Or so I could drive the older children to school. I wish I had this with our first 3 children!
