I always make too much - it is an issue with all foods. If I host a family dinner we have leftovers until the dawn of time, a birthday party gives us extra food for a few months, like I said - I have issues.
Too much smoothie equals popsicles and bite size treats. These are extremely helpful when E2 has decided she "doesn't like the smoothie anymore." For some reason, E2 will eat the frozen version of the smoothie more often than the drink version. E1 drinks and eats it all.
