Listen as long as you know she's eating healthy and active I would not wrry too much about it, esp. since the dr. told you its okay. Everybody has a dif. frame and if you worry too much about it she's going to catch on and figure out that something is "wrong" with her appearance.
You DO NOT want to give your child body image issues and all the incumbent issues that come with that (the low self-esteem, depression, eating disorders, body dismorphia etc.)
So I'd suggest for your sake and you daughters you learn to be happy with her and her body.
Keep making sure that the food you provide is healthy, that she's active (take her to lots of parks, pools, maybe sign her up for soccer, dance, gymnasitcs whatever she likes) and then just sit back and tell her everyday how absolutely gorgeous and yummy she is.
(BTW, my daughter is also on the round side so I do understand your concerns and the above is what I remind myself everyday
