Oh, that would be me. I found it sort of surprising that it applies to me

It may sound (and probably is) really bad but I keep thinking more about DS6 than DS4 and his academical needs. DS4 will be in K next year and will be homeschooled together with his brother. Wish me luck, a lot of luck.
He will most likely attend a private school 2 afternoons/week to be with other kids. Their afternoon program includes only the fun stuff (lunch, recess, drama, art, music, cooking, PE, etc.) so I won't have to worry about the academic part of it. We've done the same thing with DS6 this year.
My biggest concern is how I will manage to hs both of them. The dynamic will be very different. I haven't started looking in any curricula yet. I will probably wait till summer when I know better where he is.
