Do you have any kids yet?
So when my does are in labor, I subscribe to the school of thought that you check on things before bad has a chance to get real bad. If the "bubble" has ruptured, I immediately, feel around to see what's coming. You want a nose and two front feet, with the nose on top of the feet. I check to make sure this is the presentation coming because if they are backwards or upside down or something it's easier to fix sooner rather than later. Some does progress really fast and some don't. First timers tend to take longer, and the first kid out will take longer than any subsequent kids in there. Helping a doe kid is largely instinct and knowing your goat. Some folks say a kid out in 30 minutes, some say an hour. I go somewhere in that time frame. If my gut is telling me that nothing is progressing or something is wrong I dive in. It does take awhile for the doe to fully dilate and open up to get that kid out. Especially if it's a big single.
It's a fine line, lol.. don't be afraid to let nature take it's course, but don't be afraid to help either. If everything is presenting normal (two front hooves, one slightly ahead of the other, and a nose) let momma work on it for awhile.

Oh and don't be surprised if you spend lots of time with her waiting, then go in the house for 5 minutes and come back to kids. Some does just like to do it alone. I have one doe, that's kidded 5 times and I have yet to see her kid, lol.
And keep us posted!!
