How do I tandem breastfeed with a greedy toddler?

Erin

Okay, so maybe she's needy, not greedy. Either way, she has no interest in weaning yet, and I am not sure how to explain to an almost-2-year-old that the new baby is going to feed first and more often that she can. I made plenty for her as an infant, plus more, but I am concerned that she will try to feed like an infant again when I have that much milk again and I'm not sure how to handle it. There doesn't seem to be a whole lot of specific information about tandem nursing in general. I know a lot of people find it weird, but I don't want to force my first to stop nursing just because of a sibling.
