Yeah, there's a good reason why you need a special teaching qualification and often a master's degree or equivalent in many countries to teach kids, even elementary school kids. You need to have excellent pedagogic and child-handling skills, very good writing skills (grammar and spelling), and have a rather solid knowledge of pretty much everything else (especially basic history, geography, biology, physics, chemistry, and nowadays how to use a computer). Never mind the fact most people are mathematically illiterate and complete unable to teach basic operations. Plus, you'd have to teach a three different levels simultaneously, meaning you'd go either way too fast for the youngest, or way to slow for the eldest. And there's a solid chance your kids will not see you as a valid authority figure when it comes to dispensing academic knowledge. Even if they do, they'll likely be wrong, as you likely didn't throw away years of academic studies just to end spending your day cleaning after the dumbass you call your husband and washing his skid marks on his undies. So, yeah, for the love of everything, including your own kids, DON'T HOMESCHOOL!
