So LO (almost 7 months) is eating LOTS of solids lately and he particularly loves oatmeal mixed with his fruits and veggies. However, I am having trouble keeping up with pumping the extra ounces of breastmilk needed to send in to school to mix with the oatmeal. Sooooo... my question is, should I start breaking into my freezer stash (really don't want to!), mix it with water, or buy some formula to mix in with the oatmeal? His school said they could just mix it with water, but I would think formula would be more nutritious than water, right?
