My daughter starts preschool in two weeks. She's going through a phase where she's extremely picky. It's very annoying. That said, she will suck down a smoothie.

Have you packed them before? Will it stay nicely in a stainless steel straw cup or something? If I make it with fruit I can't imagine even if it separated some that it would be that gross..but I'm not sure.

She's only going to be there 9-1, but they do eat lunch there. So in her bag for a couple hours.
