I sort of did this in college. I had so little time between classes that instead of visiting the caf at lunch I'd visit the canteen and grab things like apples and bran muffins and other storable portables and eat them while I walked. It did pretty much turn out to be about 5 meals a day.
Once babyjama is eating more finger foods you can do this by simply eating when she does. Most peds recommend 3 meals plus 2 snacks. And the snacks should be structured like a meal: fruit/veg, protein and carbs. There's a cool graph in Ellyn Satter's "CHild of Mine" that shows how the different food types (fat, protein, carb and sugar) provide energy at different times and if you have them all in a snack then there is no energy spike or crash.
