HELP WANTED: Children's Book

I decided I want to write a children's book. I'M REALLY EXCITED ABOUT THIS IDEA! I want to write a children's book with a specific purpose. I think a picture book for parents to  read to their child if he or she has cancer would help prepare kids, sibling and parents for their journeys. It might at least be a tool to share with children to help them feel as if they aren't alone. If you want to see a book out there that could help families like mine in the future, please keep reading how you can help.

I need advice and direction.

Do you know of books like these I can read?

Do you have a favorite children's book publisher?

Do you have advice about writing books?

Do you know someone I should talk to about writing a children's book?

I like to write, but I'm not going to pretend I'm an expert on all types of writing. So HELP is WANTED!

Thank you so much in advance.

BTW - My friend loves me and bought me a NAKED eye shadow palette and I'm really excited. HOWEVER, you can't see it behind my glasses. I have small eyes and my eyebrows are low. Any beauty experts out there want to give me advice on how to make my eyes pop behind glasses?  It's also really nice weather so I thought a photo of me might shake things up instead of my children.
