Really random question. DS is 4 months now, and about a month or so ago I noticed he had crusty bits behind his ears. Deciding I was clearly a terrible skank of a mother, I put moisturiser on the area to loosen the crusty bits, then have made a concerted effort to always clean behind his ears every day. He still gets it.
DH reckons it's from his milk when he feeds, but I'm sure that runs onto his neck, not behind his ears, and surely daily washing would stop that getting nasty.
Is this normal, or does my child have some bizarre ear crust issue?
