I would even go as far to say do 3 days a week... mon wed and fri... when you do just tues and thurs, those tuesdays are going to be HELL... for you and him!! he will have 4 days at home then be thrown back into school every week. Mondays are always hard (even for adults) after having 2 days in a row home and i think its never too earl to start preparing them for MONDAYS!
