I know you're the primary breadwinner. That's just one more reason for you to not take that option. Besides, as so many others have pointed out, they seem to be jumping to that option because it's the easiest FOR THEM.
I have no doubt that Wee would flourish in home schooling. But you need to earn your income, and home schooling should not be proposed when they have other options they haven't even tried. Following the IEP would be a good start.
If ever you do get to the stage where you can, or choose to, home-school wee, let me know and I'll give you some pointers on how to avoid being in each other's pockets. We've got a system with difficult child 3 that works, that allows me to leave him alone (now he's 16 especially) and even when I'm home, unless he is struggling, he gets on with his work without me necessarily needing to talk him through things. If I do, we have an intense half hour or so discussing the topic, then I leave him to continue alone. He's learning to work independently in tis way, and learning that if he doesn't do it, the work doesn't go away but it waiting for him always.
But that isn't your issue now. Home schooling should not be getting suggested until the school has really worked PROPERLY on the problem.
