Let me tell you, i'd rather milk 2-3x a day, then be attached to my pump. I pump every 2-3 hours for my toddler (he was a micro preemie born at 24 weeks, he nursed until almost 2, but weaned and stopped gaining weight... ugh. so I had his sister, started pumping and he gained 5lbs in 6 weeks after her birth.) ANYWAYS... milking a freaking goat, would make my life *easier* then how much I'm attached to my pump for him.
I nurse my kids to make my life EASIER - not harder! LOL He's worth it, don't get me wrong, but milking a goat will be WAY less work - none of my kids can drink cows milk with out green runny poo and throwing up... but they've all been able to drink goats milk okay.
We buy it at the store, and its 4-5 dollars a quart, to 8-9 dollars a gallon... at the rate my older kids drink it, it IS actually cheaper, to milk my own goats.
