She’ll either learn to like oatmeal or learn to cry with her mouth closed (5 months old)

Just when she was getting used to rice cereal we went and changed the rules and started feeding her oatmeal. So now I spend long intervals “buzzing” as the bug/spoon flies to her mouth to deliver the food and making train noises and attempting plane noises which it never takes me long to realize I don’t REALLY know how to do… Then there is singing – how I am growing to hate these songs. But when she’s getting tired, it doesn’t seem to matter, she just cries. And when she cries, she opens her mouth. And in goes the oatmeal.
