If she's aware of what's nutritious, then she's making a conscious choice and, since she doesn't seem to be asking for advice, I'd mind my own business.
The foods we allow our children to eat are a touchy subject and it can be very difficult to really know what is going on.
For example, dd, who is 5 y.o., isn't really hungry during the day, but she'll have a super-healthy late dinner every single day. She'll have a so-so breakfast (whole-wheat crackers and goat cheese), she brings a healthy lunch to school but doesn't really eat all of it (today, for example, it was pasta, cherries and almonds). Then she'll have something when she gets home from school (like some pita bread with greek yogurt). And then, around 7 pm, she'll have a huge bowl of organic rice pasta with lentils and fish, a pear, a tangerine, some papaya, broccoli, grapes and mango... I don't know... I have a friend who sees her eat and I know she doesn't believe me when I tell her she has healthy food (and in large portions) at home. I'm sure she thinks I'm a lousy parent and I am spoiling my dd letting her eat whatever she wants.
