For the last few weeks LO has had huge patches of rough alligator skin on his body. Half of his trunk and one of his thighs is covered in it. It isn't red or inflamed (unless he gets really hot and then it shows up in red patches that soon disappear) and doesn't seem to bother him. We have tried piling on the lotion but nothing helps. Anyone's LO have this? Did you ever figure out what it is? Anything that helps?
