Feedback on ideas

Soo-I have a couple of ideas for stories I wanted some feedback on.
I may have spoken to someone(s) about them, my brain is a seive.

1)Mailboxes. This will either be incorportated into the story I am currently working on-the one I brought the first chapter--that seems to no longer be the first chapter--about the girl who..ok I am getting distracted here. The mailbox idea is a children's story idea where at night the mailboxes gather and 'gossip' the days events and try to help out their people. But I keep coming up with mushy ideas--need some good ideas still about the problems they could help with.

2) A Christmas Tree that turns into a Valentine's Tree that becomes an After Tree for the birds and squirrels and then becomes alive or maybe not.

Very rough ideas.

3) My YA novel is of a girl who has some kind of problems--CP?--and she finds a tree and a path to another world--maybe where storybook characters are alive and living together or maybe not.

Lots of ROUGH ideas.

What is everyone else working on?

Hope your break is great!
