Hi Jacqui2011: I want to first say that I'm sorry you went through that. It is a great feat to overcome an eating disorder.
Second, I would worry about her depending upon circumstances. Is she so fussy that she is not getting adequate nutrition? Has she lost weight or is she not growing properly? Does she have enough energy during the day to do the things most 10 year olds do?
If you are super worried, I would consider a basic visit to the doctor to make sure she is growing normally, maybe basic blood test just to make sure she doesn't have an infection or something that might contribute to aversions to certain foods.
Lastly, I would recommend a daily vitamin supplement, as approved by your daughter's physician ( we love the gummy vitmains), and think about supplementing her diet with a product like Pediasure. It contains a lot of basic nutrients kids need to grow. It comes in several flavors, but you can also make it more attractive by blending it up with fresh fruits, adding some low fat frozen yogurt, or what not to make it taste better.
You just need to find that balance with her and be sure you are emulating healthy eating as well.
Wishing you the best of luck and hope you both are doing well!
