I second the rice and boiled chicken. It was my go to solution when Pyrate had problems and always worked. I used to keep rice already cooked in the fridge most of the time when he got older as he had a lot of problems. With Raina I use oatmeal as she is allergic to rice. If you get the Quick Quaker Oats you can have it ready in a minute in the microwave.
