Regarding socialization and extra-curricular activities, like many others have said, we've had to scale DOWN on the amount of time we spend participating in these options. We have an incredible co-op, a huge community of church-based homeschool groups, and lots of sports teams/leagues that are independent of the school system. It became overwhelming at one point and we had to limit our outside activities to two field trips/month, and one extra activity (karate/jiu jitsu 2 days per week).
It's so funny to me that one of the first thing ppl ask when they learn that we homeschool is, "Yes, but what about SOCIALIZATION???" Like our kids are living in a cave, doing school by torchlight , isolated from other humans

. Most of the homeschooled kids we know are very well socialized, because they are, in fact, socialized within their family. Not to be ugly, but I don't want my kids socialized solely by a group of their peers (Lord of the Flies, anyone

). Our kids are socialized by actually living a real life. Sitting in a classroom 8 hours a day is not socialization. Going with me to the bank, grocery, other errands, interacting with other adults and kids in the real world...that's socialization. I don't get how ppl think running between classes in the halls of a school building is "socialization."
