This kid's kryptonite is his asthma. I love love love what solid sleepers my kids are. They can sleep through anything. At night when I hear him wheezing, I put on his on mask and his hand immediately goes up to clutch his mask, almost as if it was a security blanket. While I'm grateful for the medicine, the technology, and for his ability to sleep soundly, it tugs at my heartstrings every time.
