<rant> What genius decided it would be a good idea to package sugary juice inside a pillow-shaped, squeezable pouch? </rant> Sandy has an answer:
For the toddlers that insist on holding onto their own juice pouch/bag, it takes about 2 seconds before juice spouts out and gets everywhere. Instead of the fancy "juice box buddies," we use one of the sippy cups with handles. Take the top off and the juice pouch fits in snugly. When my son is ready for juice, we stick the straw in and it works great. We make sure that we take the top along as well so we have a sippy cup to turn to if needed.
