You'll be connected to your goats!!! They behave similarly to dogs in that respect. Kidding time is usually around April. You'll do best if you buy some bottle babies and finish bottle feeding them. That way they'll REALLY bond to you. They'll consider you to be their parents.
Regarding milking, all dairy animals are the same, you have to milk them twice a day, every day, no matter what. If you want to milk them sooner, you can buy adult does and a buck. Or you can find someone with a buck who will charge you to breed your does.
When we had our dairy goat farm, we were breeding 60 does a year, and our does averaged 3 kids each, so we had A LOT of kids. We kept some kids for the herd, but we sold most. We had no problem selling kids if the price was right. We put a lot of work into our genetics and we had good milkers with a high butterfat content, so our kids were sought after for milkers. And all of our kids were bottle fed, so they were also sought after for pets. We de-budded their horns at a few days old, and gave them all of their shots. And my wife would neuter the bucklings for people who wanted them for pets (intact bucks get rather stinky at breeding time, and they get pretty focused on breeding, so they make better pets as whethers). We NEVER sold kids for meat.
Goats are a lot of fun, and even your milkers will be your pets. We had over 100 goats, and every one had a name and was a beloved pet. And there's nothing cuter than goat kids.
Oh, I thought of a con. Because they are sooo smart, they will learn how to operate most gates. You have to be very careful about having gate latches that they can't figure out how to operate. I even had to move the light switches in my barns so they were out of their reach. They would love to turn the lights on at night. People wouldn't believe it until they saw it, but when I saw the lights on in the barns, I'd yell out, "You girls (or boys) turn out that light!!!", and the lights would suddenly go off. They are SMART. You can also train them to do lots of things. They enjoy learning tricks, and they enjoy showing off how smart they are.
Also, you need to keep your bucks and does separate, or the milk will absorb the bucks stinkyness during breeding season.
I'm sure you'll have more questions, just let me know.
