I am going to try to go light this year too...I wrote out a list and am telling people who ask me to get stuff on it so I can cross it off so the below are not going to all be from me. Here's my list:
For JT - play doh, Mr. Potato Head, Legos, play food, stickers, broom/dust pan, basketball hoop, possibly a very small trampoline, and I want to get some type of bike or motorized ride on car or something. Of course, some will be for birthday too! I also really want a Radio Flyer double wagon for the 2 kids. Maybe Grandma will hook us up! I'll have to look up the Fisher Price zoo. He has so many Little People things like the school bus, dump truck, safari, etc. but only sometimes plays with them. Hm.
For Timmy - that piano thing that you kick (remember hearing great things about it on here), a swing for outside to hook onto our swing set, and a toy box. Not sure what else - JT pretty much has a ton of stuff that Timmy can now use.
