Bear in mind that goats, like most animals, love routine. Ours insist on same time, same place, same order of milking etc. I changed a couple of the boards on the milking stand the other day as they were getting rotten. The girls refused to climb up as usual and had to be coaxed, then spent most of the time during milking peering round at the new wood...oh and I can't milk them if the cat's in the byre either!
Honestly though, try to do the same things each day in the same order and you'll be surprised how quickly she'll settle.
