Mmmmh... not sure how I would go best forward on this. Once you start milking you would have to do it at least once a day, so when you are away someone else would have to do it. You could possibly wait and keep her ration as it is now, but I'm not sure she will keep her udder if not touched for long after summer (mine -in the Scottish Borders - usually drop sharply the first week of September). You may be lucky.
Or dry her up and hope she comes back into milk next spring....
Maybe not so great advice from me then..., I never milk udders on goatlings and all of mine are mated at 18 months to kid when 2 years old.
