So I just reread your post. You're nursing a 10 month old 7 times in a 24 hour period. Isn't that appropriate? I know that she sleeps a longer stretch, but maybe you could do a dreamfeed when you go to bed and get an extra feeding into her?
I know how stressful and nerve-wracking it is when they won't eat and you've pumped all this milk and they only drink the tiniest amount to get by. But now I honestly believe that they won't starve or dehydrate themselves. They are accustomed to being in charge of how much food they take in and it is so much harder for us when we can actually measure their intake.
