Finn's hands and feet just stopped peeling recently. I put aquaphor on them every day and baby lotion on the rest of his body after his baths.
I don't know about heat rash. Maybe some goldbond powder to keep it dry? I really have no idea, I don't even know if you can put goldbond on babies.
As for the cord, we didn't touch finn's except to blot it dry after sponge baths. We were told to leave it alone and it would fall off on its own, it fell off at 8 days and now at 16 days it's still a little bloody every now and again. I just wipe it with an alcohol swab every day or so.
I want to see more pics of reese!
