I'm going to take a try at this and let the experienced aunties correct me if I'm wrong but I think you have a while to go. Baby has to move forward and I do believe you'll see waxing on the nipples. My mare foaled last night and I just knew she was going to foal because she started leaking and also her hoo haw became very elongated. Now I'll wait to see what the other aunties say. She's a beautiful mare!
