Thanks for the advise on the calcium supplements. I called one vet and he said that he thought it would be alright to supplement calcium but he doesn't deal with a lot of yorkies and couldn't tell me if there was anything that would effect the breed, so I'm not stopping there. Soooo, I've called my other vet and he should be getting back to me this evening.
One more question though...has anyone used Esbilac Milk Replacement? Also if y'all could see the attachment, I found the Ready-to-Feed version and the nipple is a little bit smaller than Koko's nipples. Will this work as a nurser? Has anyone tried this?
