if you're doing it right social isolation isn't even a thing. trust me, i was homeschooled k-12 and other than my dissociative issues which have nothing to do with how i was schooled im fine. im a natural introvert, but feel like i get along with any other people in my life totally fine.
with that said, just make sure you read up on it. in a lot of places its relatively easy and not as ostracized as it was in the late 80s and early 90s. it's a good possibility for every kid, but take their opinion into consideration as they grow up too. it's not a situation you can't reverse either. just keep that in mind :)
