Ems, that does suck (pardon the pun LOL). I went through that with my oldest, Rafe. I weaned him late at about 10 months. I'd had him separated for several months and figured he was done until one afternoon when he escaped his pasture. First thing he did was go to the pen where his momma was and start trying to nurse her across an electric fence
. Another few months though and that was all done and I could turn them out together without issue.
The one that started really tripping me out is Bessie, my Belgian mare, only ever had Rafe. He was her first and only foal and that's been 4 years ago. When I brought Talyn home and was finally able to turn her out into a herd, she worked up to it and started nursing on Bessie
...and Bessie started making milk! I think she's just a hussy for being a momma LOL. Now that Talyn's turned out with all geldings, I don't have a problem anymore.
As for your feet, about once a week, scrub them with a pumice stone after soaking them in a tub of warm water for a while. After that's done, dry them off and apply a generous coating of either Vaseline or some of this stuff
. Put on a pair of lightweight socks and go to bed. By morning, you'll be shocked at the difference. Continue with the nightly application of the moisturizer and socks and then just scrub with the stone every couple of weeks or whenever you feel like you need to.
