It's possible that your son craves carbs as a way to get his blood sugar up. Giving him eggs for breakfast is a good experiment. With mine, we try making sure she has some meat of some sort for breakfast. If he likes bacon or ham, you might try that on the side. If it produces an improvement, there's nothing written in stone that says you HAVE to serve "breakfasty" stuff in the morning, as opposed to quickly nuking some "lunch-style" stuff
