Yes, congrats, Isa. I'm sure this will get easier and easier, but it is a good bit of work!
I know several people who are adamantly against kids learning independently on a computer, but it works really well for my girls for limited amounts of time. Perhaps the kids could do maybe a quarter of their work via computer programs during the day, this might free you up a little.
Personally I think there are wonderful online programs and software for learning.
Another question, are the children learning in english? Forgive my memory, I know Dutch they are not fluent in but I couldn't remember about English. If so, I have some specific links I could give you that you may like.
