Headsupport for carseat

The carseat, at least mine (Graco) came with a flimsy head support. I had gotten a head support to attach. It had 2 layers. You don't know how big or small the baby is going to be! We didn't need the 2nd part, since I had an 8lb baby with a good size head. We did need the one piece. It was cotton, so nice and soft. When he got bigger we did put the one that came with the carseat back in, since he didn't really need it as much.
