I just received a Revolution Foods Sampler from EcoMom. My preschool-aged girls love the Organic Mashups Squeezable Fruit. These are great on-the-go snacks or to add to a child's lunchbox. They are like applesauce in consistency. We tried three flavors: Berry (Strawberry, Blackberry, and Blueberry added to the Apple), Tropical (Banana, Pear, and Mango added to the Apple), and Strawberry-Banana.
We also got three kinds of Organic Sammys -- snack size sandwich bars. These look yummy, but I'm saving them for our plane trip next weekend, so I'll have to get back to you on whether we actually like them. :) We have Grape Jelly & Peanut Butter, Strawberry Jam & Peanut Butter, and Grammy Sammy (Honey Graham & Strawberry Yogurt).
Plum and Revolution offer a wide variety of products, so be sure to check them all out, whether your child is in a high chair or using a lunchbox.
