Nina,
I am praying for you and your family to get through this rough patch. We are all over the board on where each child is in each subject, but they help each other and we take it a day at a time. Just last week we started on our history lessons again after quite a break. They enjoyed it so much that all we did that day was history and got nearly caught up. I plan on doing the same with math one day this week. On top of the kids schooling, I am studying midwifery.
I also wanted to speak to your morning sickness. Eat lots of small meals, high protein. The longer you wait to eat, the more nauseous you can become. I was sick for most of all 3 of my own pregnancies, and I remember how very tough it was to try to eat frequently. Keep nuts (almonds, cashews, etc) on hand for a quick snack to keep the nausea at bay. You may be able to find a surgeon who is skilled at removing gall bladders even during pregnancy. One of my former clients had to have it done. It required a couple extra days in hospital to monitor her and baby, but it was successfully done and the rest of her pregnancy was much easier.
Best wishes,
Olivia
