How does BD Regina keep fit? She seems fairly busy, tasting very sugary treats often and is described fairly thin. Does she gain a lot of pregnancy weight or is it just a small cute belly? Will we see her getting annoyed at how big she is? :)
Y'know, the easiest time I ever had losing weight was when I was working 8-hour retail shifts on my feet. You burn a surprising amount of calories by standing/walking/hefting and just doing stuff. I don't think Regina sits down a whole lot between 4am and 3pm, so that helps keep her a bit more svelte. And I don't think she indulges too often in the food around her -- she'll eat a croissant for breakfast or something, but she probably brings actual lunch, or just has a croissant sandwich. Which isn't the healthiest option, but it's not the worst. And NYers walk a lot, so there's that.
She probably gains a little bit of weight during pregnancy, but not too much. I think Cora had fairly high standards for Regina and how she ate and how she looked, and I think that's sort of internalized for her. So she's aware of gaining too much, even if she's pregnant. She'll gain an appropriate amount, she'll probably want to drop a few pounds after the baby comes, but she won't gain a lot. Robin will tell her she's being ridiculous, that she does not need to lose that extra ten pounds she gained, that she shouldn't worry about that. She's been through pregnancy once, so I think she has fairly realistic expectations about how big she'll get, but it will definitely annoy her once the belly starts getting in her way. And a job that has you on your feet all day isn't the greatest thing for you when you're sporting that baby belly, so she'll definitely be frustrated by the back pain and such once she gets big.
