Your baby sounds just like my Mylee. I've posted before on Mylee's extreme anxiety issues. I never could crate train for the same reasons you posted, and she either jumped or climbed out of play pens. What I do have for her is Moka, our other dog who graciously took on the roll of babysitter. She gets great comfort from Moka when the two are left home during the day. Without Moka I know we'd be dealing with many of the same issues you are dealing with. I will say, however, we have seen great progress through consistency and regular training, and I get great satisfaction seeing where she has come. Mylee is very, very smart, and it seems the more we teach her and work with her, the better her behavior becomes. I don't think this is the best scenario to recommend another dog, so I wonder if a doggy daycare wouldn't be the best option for you and your baby during the day.
