To answer the questions, baby is slightly premature, 36 weeks. Everyone is doing pretty well but baby is still figuring out to regulate temperature and blood sugar so discharge isn't guaranteed for Friday. But they want to be ready if it happens.
They have a pack and play where they are, and almost all the things back home from older sibling. They're staying with mom's mother who is great, so they have some support, and older sibling is happy and well cared for. Plus since it's her mom, it might be less awkward for her than being with IL's.
Mom EBF the older sibling, and was planning to try to do so here too, but baby had formula this a.m.. They should be able to get a short term pump rental from the hospital, since they have a pump waiting at home. Anyway, she'll probably need both sets of stuff. I was thinking I'd just get those little 2 oz bottles of formula so they don't have to wash bottles, but waiting to hear what brand/type worked in the hospital.
