I have a 2 year old boy. He went to Disney at 7 months, 17 months, 26 months, and in november he will be 32 months old. We have always taken him on everything we can. You never know how your children will respond and when they do, it's a memory you will have forever.
Like my son pulling himself into a standing position so he could dance to the music on IASW. Or reach for the bubbles while watching the muppets, laughing at Donald on Mickeys Philharmagic, the expression on his face when he realized how big Buzz actually was. And mostly when he was 7mts how he responded to Mickey Mouse for the first time. He reached up to his face and grabbed his nose and squealed. Of course I was in heaven!
Some people say don't take them until they can remember. No I'm sure my son won't remember all of those things but I sure will, and it's worth every penny!
