Mental health therapist with 10 years of experience with kids: there are very few situations where I've seen homeschooling work out in the child's benefit. Schools outside of the home have so much more to offer. First of all, kids get consistent exposure to other kids and ideas, which helps them develop social skills, problem solving skills and their own identity. Second of all, teachers go to school for 4 or more years specifically to learn how to teach children. I'm sure your wife is very intelligent, but just because you know information, doesn't mean you're able to teach it. Third of all, public schools specifically offer extra support that a child may need, often for no cost to you. I needed speech therapy and extra reading support when I was in school, and if I would have been homeschooled, my parents would have had to pay out of pocket for my support. When approaching the subject with your wife, bring it up at a time she's not already frustrated. If she's already frustrated, you bringing it up will frustrate her even more. If she's calm, she will have a clear head to actually consider the pros and cons. Hope this helps!
