These are perfect for keeping my 2 month old from scratching his face.  They probably keep him warm too, which in winter is an added bonus.  My only complaint is that now that my baby is 12 lbs, these are really tough to get on him. Also, they shrink as much as you'd expect for 100% cotton (a lot).  I've looked everywhere and can't find mitt-cuff onsies for babies bigger than 12 lbs.  Anyway, if your kid is still pretty little, these will work.
