Need ideas for cheerful gifts for a severly sick child...also for the mom?

We just learned that a 3 1/2 year old in our family is very ill. What are some cheerful gifts that would be appropriate? What about the mom that is going through all of this? I don't want to send flowers or anything else that would just remind them of being ill, rather something that would take away from the "get well" theme, rather just show encouragement to stay strong.
