These are amazing. The hype is for a good reason. Even my husband said he'd put them on a top five list of things you need for a newborn. We used them all the time and washed them regularly even though we had eight in total. We used them for burp cloths, swaddles, car seat covers (in one layer—don't fold or your baby could overheat), and even play mats. More than anything else, we used them to clean up A LOT of spit up (we were blessed with a baby who liked to make a mess). Oh, and in a pinch, our daughter even liked to play with and suck on these blankets.
As a side note, we were gifted a pack of smaller, similar towels of a different brand and—while they weren't as good for swaddling as our baby got bigger—they were not that different (in case you need to save a buck).
