Help for a friend with Leukemia and young children

I'm a member of medhelp because my mother was dx with ovarian cancer in March, and the people on that forum have been amazingly helpful.

I'm coming here for your help, because a friend of a friend was recently told she has Leukemia. She's 30 and has a 4 year old and a 1 year old.  She's asking for help in the following...since she'll be in the hospital over a month.

- Suggestions for books for young children whose parents are in the hospital for extended treatment
- Resources for parents/caregivers about talking with young children about cancer and long hospital says
- Resources for people in their 20s/30s who are going through cancer treatment

Any help you can provide would be so greatly appreciated.

Thank you,
Meg
