Since birth, Matthew Boler had an odd-looking head that was narrow and oblong, but his parents didn’t think much of it until his 2-month checkup. At Texas Children’s Hospital in Houston, doctors found that Matthew had a possibly dangerous condition called sagittal synostosis, meaning his skull had fused on the back of his head too early. As a result his brain had no room to grow, which led to his odd head shape.

Luckily though for the family, they caught it soon enough that doctors were able to do surgery with small cuts. Matthew had to wear a helmet 24 hours a day for 4 months, but today it is hard to tell anything was ever wrong with little Matthew.
