Hello neighbor!
We have been homeschooling in south Florida for 4.5 years. We were somewhat "accidental" homeschoolers ourselves, and have grown to truly love the lifestyle.
My kids were in traditional school for a long time, so we have a number of traditionally schooled friends. At first I was embarrassed to say what we were doing, but I'm long past that! :P
My approach is to just say what has worked for us. When people get on a tirade about how "I could NEVER homeschool and HOW do you do it?" I just let them rant. Unless I believe they're asking me a genuine question I don't bother engaging. I just say something like "well, it's been great for us so far, but everyone has to find what works best for his/her child." And that's what I truly believe.
I would also join a homeschool support group - it helps to be around like-minded families. Plus it sounds like your daughters are getting close to those middle school and high school years where you can take advantage of some of Florida's fantastic benefits for homeschoolers. If my younger son plays his "cards" right, he could graduate from high school with close to enough credits for an associate's degree (from college). Especially if your daughter is a talented student, this is something to consider - it can save you so much money during those college years.
Good luck and I wish you much success and happiness!
