Welcome to Yorkie talk
congratulations on your new little babe, chickensmith had lots of good suggestions and I would definitely follow up with some research on signs and symptoms and treatment of hypoglycemia. That's great that you have already got her to the vet and are being so proactive. There is a lot of good info on here, I like the name Gwendolyn and you could call her Gwen or gwennie
can't wait for pictures!
