Sky, I'm sorry to hear that. A number of years ago, I had a heifer that initially cleaned & claimed the calf, but after 2 days or so, she decided that she didn't want to be a mother anymore. I got a couple of bottles of replacer, water, electrolytes etc into the calf to get it back up to speed. Then I penned them up together, and played that rodeo game for almost 2 weeks----- get cow in the chute, let calf nurse, while cow wanted no part of it------- and she never did want anything to do with it. I bottle fed for a while, then sold the calf to a guy looking for a bottle calf and sold the heifer to another guy, who was willing to give her a try. I found out, about a year later, that she calved again and this time all was well.
Hopefully you can get that calf back on its feet (so to speak) and fool around with it & the mother and she'll accept it. I've seen it work with some.
Good luck.
