Grazing is okay, but it does make it more difficult to keep track of eating enough or not going overboard on certain things. As long as you eat 3 meals and 2-3 snacks (or the equivalent in grazing, making sure you get enough vegetables, etc.) throughout the day, it doesn't really matter what you call the meals or what kinds of foods you choose for them, such as having breakfast foods when you first wake up, etc.
With your odd schedule and so many responsibilities, it makes it even more important that you take care of yourself by eating properly.
-- food lists, portion guidelines, etc.
