Squooshi Reusable Food Pouches
My wife recently found the Squooshi Reusable Food Pouches. They make it possible to buy a big tub of applesauce and make your own applesauce pouches. If he wants a second helping, all you have to do is refill it. They are incredibly easy to clean with warm water and dish soap. The bottom is sealed with a high quality zipper, and we have had no issues with them accidentally opening or leaking. They come with a reusable twist off cap for the top, so they are easy to travel with.
