S.M.
I think this sounds pretty normal. My oldest was on this same type of schedule at this age.
My only suggestion would be to try "cluster feeding" before bed at night. I don't know what your evening feeding schedule is, but if you were feeding at 4pm, then at 8pm; to cluster feed you would add one more feeding in around 6pm to build up a bigger "reserve" for night time. I think I read that in the Baby Whisperer book, but I gave it away so I can't verify.
But, this does sound pretty normal and 8 hrs + is still really good and if she goes back down until 7, that's great too.
