Nixon's worn his plagiocephaly helmet for a month now. I can definitely see a difference, even though it's slight. You can tell his head is not cone-ing like it was in the picture below on the left. Yay! Things are happening! When he first went in his head measured at 98% (It should be around the low 80's). This week his head was measured and it'd gone down to 94%. We still have a ways to go, but it's going in the right direction!
