Hi Angela!
I tip my hat to you for introducing your son to Walt Disney World in his toddler years. Both of my children had their first Disney vacations before their first birthdays, so I'm a believer in giving youngsters those special opportunities.
My children are still pretty young, so I often have people questioning my decision to take Disney vacations because "they won't remember any of it."
My response?
They may not remember every hug I give them, but that's not going to stop me from hugging them as often as I can. Nor is that going to stop me from telling them that I love them, telling them how proud I am of them, or just holding them in my arms.
I want all of those actions to shape the bond I have with them...including my love of Walt Disney World.
That being said, I think you'll find that everywhere you turn in the theme parks and resorts, your son will be exposed to some type of sensory experience. I let my children be the guide - if we come upon something that excites their senses, we stop to experience it as long as they'd like.
My best piece of advice would be to keep a very relaxed schedule on your trip. That way, you can allow your son to stop and take in the sights, sounds, smells, and even tactile experiences he finds to be stimulating. These can come from a variety of sources (e.g. attractions, parades, shows, or whatever else he stumbles upon).
Here's a little tip from your buddy Derek:
There are quite a few attractions without
height restrictions. You can find a list on DisneyWorld.com and do a little recon to map out the potential "must-do's." If you have any questions about particular attractions, feel free to write back and I'll be happy to share insights on how my children reacted to them.
I hope that helps!
Best regards,
Derek
