My kids really love these 100% pure fruit snacks and they are ideal for their lunches. I usually freeze them so when lunch rolls around at school they are easy to drink and keep the rest of their lunch cold. They come in four flavors: Strawberry and Banana 16g, Mango, Banana and Orange 20g, Peach and Apple 16g and my kids favorite, Apple & Grape 19g. They are sold individually for about $1.20 each.
I purchase PR fruit pouches at our local healthfood store in the infant food section. Click on the store locator if they aren't stocked in your local store or the Amazon link below.

Here's a blurb from there website:
What's inside our pouches?
Made from pure, organic fruit, our BPA-free pouches have no added sugar or preservatives. We only source organic ingredients certified by the USDA, and whenever possible we use local suppliers in Oregon. Our 3 delicious pouches have a thick, smooth texture and aren't diluted with water or juice.
Why the pouch?
Similar to squeezable drink pouches, Peter Rabbit Organics pouches are easy to drop into a diaper bag, lunch box or purse without breaking or spilling. Unopened pouches don't need to be refrigerated so they're great for car trips, cycle rides...and for all the family to enjoy.
Ideal for ages 6 months and upwards, the fruit can be enjoyed straight from the pouch - no spoons required!! Our no-choke cap makes them safe for little ones and the larger size makes it easy to get a full serving of fruit in each pouch.
