Iam not a breeder but i have one babie that is also very attached to me, she will also make herself sick if im not with her, I went on a mini vac and had my daughter watch her only to be called home early because she was acting funny and not eating, long story short, after a vet visit, he said it was very bad anxitey and i should try to leave her more often for periods of time. thats hard to do when you know there waiting and watching for you. they can perscribe meds for this but im sure your situation is much harder being she
is expecting, wishing you the very best with mommy and her new babies
