Yes -- as many people have noticed Gavin is always wearing a hat of some kind. One of Gavin's first issues present since birth is his inability to maintain normal body temperature. Gavin was in an little issolette for most of his first year of life just so he could stay warm and grow. Currently we have an infant warmer in our home that Gavin needs to sleep under to help him stay warm.
At times Gavin becomes hypothermic which results in a very low heart rate and apnea -- so therefore he always has a hat on just to help him out. But in typical Gavin style it's not always that easy because Gavin also becomes hyperthermic -- will spike very high fevers not due to infection or illness but rather his body just gets out of whack and is unable to cool.
If anyone has ideas of places that sell cool hats I'm always looking for them. His head is getting way to BIG to squeeze into little infant caps!
