These are a must have when you have a newborn. The mittens we buy usually don't fit our LO because they're too big or too small. The elastic band around them just aren't great. But with the onesies w/mitten cuffs, it makes life easier and laundry more pleasant. One of my only issues is that the material becomes a little rough after a few washes. I wish they used a softer cotton or blend. But regardless this is a good item to have.
