Since they have announced that they are ready to work, as evidenced by the tiny bit of colostrum I find every few days on them, do I need to do anything to get them ready for the job?

I got nipple butter in amongst some other things today, and I wondered if I should maybe be putting anything on them now? Kind of like putting oil on the belly to prevent stretch marks?

Side Note: DH finds the words "Nipple Butter" WILDLY HILARIOUS. I cannot believe he is going to be a parent.
