"It is a miracle. Josie is the most energetic, busy little almost-2-year-old," Michelle told the mag. "She is short, and yet she can keep up with the big girls and she thinks she is just as big as they are. We are amazed at what she can do." According to dad Jim Bob, his wife is doing better than ever. "Michelle is probably in better health now than she was 10 years ago," the 46-year-old said. "She has been getting on an elliptical for about an hour a day and is very careful of what she eats."

She is eating very healthy with plenty of protein, vegetables and skipping the caffeine - along with getting plenty of rest. "We are just going to do the best we can," she explained. "I am taking a nap every day, and we are just taking good care."
