I hope you get to feeling better! Stomach bugs are no fun at all!
I also hope the spay surgery goes well! I too got diapers and they really helped us. KS had quite a few tee tee accidents after the spay. I got a onesie from WM too through advice of my fellow YT'ers. KS never even tried to pick at her stitches but I kept the onesie on a lot anyways. She recovered a lot better than I expected. I did restrict her movement, but by day 3 she seemed like her old self.
Will keep you guys in our prayers!
