S.S.
One of my twins went through that as well. He started dropping feedings and was eating about the same as your little girl for a while, but then miraculously, he's 10 and a half months now and suddenly not only has his solid consumption gone up, but his formula consumption has also increased and he drinks about 16-24 oz again every day. I suspect that it had to do with his teeth as he got five teeth within a month. His brother did, too, (the month before) but he gave up solids rather than his formula for a while. Anyway, I wouldn't worry about it. I tried to give them more yogurt during this stage and cheese, too, which my doctor suggested when my first son did the same thing, but they won't suffer any ill effects from it. Lots of babies do this.
