I know exactly what you are going through. My daughter just turned 2, and she is still pretty sporadic with her eating. As I've heard from others, and which I've adopted as my mantra, is that as long as you are offering a good variety of foods, your child will not starve herself. I've noticed that Sophie will eat very well for 1 day, then taper off for the next few. She always has energy, and is growing just fine. I've even heard that the "just one more bite" routine is not the best. Just offer the food, and when your child says no (or indicates no), let it be at that. From what I understand, this will also help prevent against obesity and other eating disorders. As long as your child continues to thrive, I would not be concerned. That said, my niece, who is the same in her eating habits, also had a vitamin D deficiency (odd, especially considering she was living in Florida, the Sunshine State, at the time). So check all this out with your pediatrician, make sure your child is healthy and growing. Then let it be, as hard as it is.
