Hi
Welcome to YT
!!!
I'm not a breeder but I have read here for a few years now, and I think everything you describe sounds pretty normal. Shoot, when I was pregnant and getting further into it, my stomach couldn't hold much food because the baby was squishing it
Maybe that's what's happening to your little girl. I also got picky
Hopefully some of the experienced breeders will come along soon and reassure you some
Best of luck to you and your little Momma, I hope her whelp is smooth and the puppies are nice and healthy
