Bald spot?

​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​We're going to the pediatrician but I figured I'd see if anyone can relate or help. My son recently developed this bald patch. The skin is a bit red there as well. He's a stomach sleeper and doesnt spend much time on his back. Just occasionally in the car seat and in his bathtub. I havent changed anything (diet, shampoo, etc). Just nervous it's something bad, though it doesn't seem to bother him. Anyone else have something similar happen with their child?
