I'm sorry if this is a ridiculously stupid question. I saw a thread just a few minutes ago about when milk came in... I was just at a birth class at our hospital and they were talking about skin-to-skin and trying to get LO to nurse pretty soon after birth. If LO is nursing just after birth, is that because my milk has come in or is LO nursing and getting the colostrum? Are they different? I kind of thought colostrum was milk? I'm sorry if this is a completely idiotic question (breastfeeding class isn't for another 3 weeks!)
