Leukemia patient Lexi Potter is one quiet, lonely child. The 2-and-a-half year old can’t go to the zoo, shopping centres or anywhere there are crowds. Even a trip to the park is only possible when all the other kids have gone home.

Lexi has an aggressive form of cancer. Her immune system is fragile, and exposure to coughs, colds or other germs can put her tiny frame under severe pressure.
