my 7 week old son has a slight bit of cradle cap on a bit of his scalp and some on his eyebrows. if i treat it now do you think that will nip it in the bud or should i just leave it to see if it gets any worse? he's only been bathed in water so far although i've used an olive oil balm on his skin after baths. a friend gave me some baby neals yard shampoo, lavender and chamomole i think - will this help?
