Lilly has been participating in a heart health program at her school. She went from two consecutive jumps to 50 at a time in about a week. She’s also been skating, with and without a hockey stick, and has a fine-looking swing with a bat. She spends more time than ever on her living-room trapeze, and she does an hour and half of gymnastics on Saturdays. Somehow she finds the energy to stay up until 10 whenever she can get away with it.
