Hey Grace!
Landen is ADORABLE! Just too cute!! I don't think you could bore us with any pictures!
I'm so sorry to hear about Corri. That's terrible. Hopefully it will all work out for the best for everyone involved. That's all you can pray for. Sometimes on the budget board they will have threads about work from home jobs if she's interested in that type of thing to work around her being at home.
Love the Tink gifts! I would check out the Creative DISigns board here on the DIS and see if anyone can make you little notes from Tink (or Mickey or whoever) for your little gift bags once you've got them together. I'm sure if you provided the details, they could come up with something cute. If I still had my computer, I would so do it for you but I'm computerless at the moment.
As for "adult" Tink gifts, you could do Disney dollars (get them on like your first day), Disney gift cards, something for the trip she'd want but wouldn't buy herself (new sneakers, socks, hat, whatever she's into). The Hallmark store here also has some very cute Disney stuff - albums and magnets and stuff like that. They're Hallmark products so you can probably get them at any of the stores.
When Tink leaves your gifts is up to you. She could stop by while Landen's in the tub, when you come back to your room, when you wake up in the morning, whatever works into her schedule.

If you're taking a bag to the park, she could always leave something in there too as a surprise.
Like your ADRs. I've got to figure out ours for our Sept trip. I'll probably hold off on getting a Disney birthday cake until Sept because that's when Dan's mom and our friends will be there so we'll be able to enjoy it with everyone.
Glad you're getting excited. September will be here before you know it! It's amazing how quickly time flies. July sounds so far away but when I sit down and think about it, it's really not that far at al!
