1. When my oldest son was 3, we were waiting for Buzz and Woody to come out of Al's Toy Barn after a rain storm. Everyone else in line had left because of the storm and we were the first ones in line. When the characters came out, my son started running around in circles, splashing in the puddles and yelling, "It's Woody and Buzz! It's Woody and Buzz!" He had the biggest smile on his face.
2. When we were at the end of our meal at Crystal Palace, we were getting ready to leave and couldn't find our 2 year old Tony. Everybody was asking "Where's Tony?" He was two tables over giving Pooh Bear a big hug while Pooh was taking pictures with another family. My husband swears he called Pooh "Daddy."
3. Tony got his first haircut at the barbershop on Main Street. Mike the Barber was so sweet and gave him all these stickers to make him feel comfortable. (We finally got one of these moments on video!) We were given free Mickey Mouse ears with First Haircut written on the back and a great haircut.
Sorry I couldn't pick just one. These are the things that stick out in my mind.
