It finally happened. Our tiny caterpillars have fled their nest and set out into the big, open world. Ever since we got our caterpillars, we have been anticipating the day that they would turn into butterflies. We sang songs about butterflies, created butterfly art and even learned the meaning of the words metamorphosis and chrysalis. We are all saddened by the fact that we had to let the butterflies go; however, we are thankful for the time that we spent with them.
