but I am worried about my son's toe nails.
He's 3.3, before you ask.
And his toe nails look like they are peeling off in layers. His fingernails are fine.
They don't seem to bother him, it's not fungus, they just grow very ragged and look like the layers are constantly peeling off.
Do I show a GP?
I can take a picture if anyone wants to see them...
