Our new swaddle wraps feature a cozy, minky fabric on the inside, and a trendy, designer fabric on the outside. They feature velcro tabs that not only keep your baby wrapped up tight, but make them much more adjustable than snaps when trying to get the perfect fit. They work great for babies up to 5 months of age (depending a bit on their size and how early they roll over). To extend the life of your swaddle wrap you can tuck the swaddling flaps under baby's arms as they continue to grow.
