This swaddle really is as magical as you have heard. With the Ollie your baby will sleep for hours the first night and you will wish you got it sooner. Best swaddle we’ve ever had for a newborn. The fabric is amazing and perfect for summer. It's definitely an investment but a very worthwhile one. Easy to use and stays secure on baby. Made from custom moisture-wicking material to reduce the risk of overheating. Easy access diaper changes accessible through opening at the bottom. Highly recommend!
