The belly exploding... happens to all of us who feed f/t from time to time. Just something that happens. I too have heard about thawing them out on their backs. I normally get them out of the freezer the night before and put how ever many I need in a babby in the refridge over night. The next morning I take them out and out of the bag and let them sit in my room and warm up to room temp. Then when I get home fro mwork or that evening... its feeding time.
