I kept a food journal for a few months, it really helped me keep count of my calories and protein. I have a book I'll send you, that is where I got my intake recommendations. It's something like, "when you are expecting twins, triplets or More" by Dr. Barbara Luke. It also has high calorie and high protein recipies in the back.
I had a really hard time, I'm NOT a big eater. But I ate a lot of cottage cheese, yogurt, chicken (baked, or in the george foreman), ICE CREAM (has lots of calories, Ben & Jerry's brand), a LOT of milk (whole milk for extra calories) I'm going to try and find that journal to see what I was eating. Oh, a LOT of spaghetti o's with a protein shake (Optimum nutrition chocolate, I could gulp it down in 2-3 swigs and it wasn't bad at all- and I'm PICKY!!)
