Put in a decent size of parlour starting of 14 or 16 units and do it once.good 2nd hand parlour not that hard got particulary in the north.
As
@Neat says no point in been a slave or expecting your father to do all.
I'm on my own here aswell with young pre school kids. We do not live in a dairy area and its not easy to get people to milk.end up training in 15 or 16 yr olds and get them for a yr or two.then there gone to college jobs etc. I have been reasonable lucky so far as to getting ones worth training cause they are scarce.
If you have an old small parlour with lots of rows i do know from personal experience that the bucks will say they wouldn't milk if they get hardship and spending time milking.
While they are young and probaly inexperienced you would never get away for a day / weekend or a holiday. And yes I have had some broseess to deal with when you get back but it's stay home or let them at it.
Alot of farms are still family labour with relief miller from time to time despite what you see in the media about calf rearers , herdsman manager relief milkers etc
