We took DS for his 5th birthday in jan. His birthday was the first day of our trip, and we let him pick what to do. Which was HS, and Toy Story ride first thing. He got to pick the rides all day, and I let him pick for dinner, beforehand, if he wanted Chef Mickeys or TRex. he picked TRex...which was awesome for him!
Special things that we did besides just the trip...
*The fun card was his, to spend on whatever he wanted...all Star Wars potatoheads
*I make everyone matching tie dye shirts, with Iron-ons, and got someone on the disign board to make him a special Toy Story shirt proclaiming "its my birthday"
* Usually, build-a-bear is our birthday tradition- we take the kids on birthdays (so we always end up with 3 new build a bears...each...between dec and feb!) So this time, after t-rex we went to build-a-dino, which was very special for him. And the greatest thing was, between gift cards I already have, and our stuff-for-stuff certificates, we only had to pay for the clothes.
