I wish I had an answer for you, but it isn't something we really deal with. My kids all molted once or twice as babies, but never since.
I don't find the board any less helpful, but sometimes it takes a few days before the person with the answer to your question comes across your question. :P
Ichthyosis-en-Confetti Type 2
