Hi Erica,
Welcome to the Moms Panel! You're smart to plan ahead for your trip to Disney Word. I have been taking my boys to Disney since they were born so I've experienced a lot of different stages. I think that if you go as prepared as possible & in the right mindset, you can have a great time. It will help to have many hands on deck to keep your son entertained. Your parents can also watch the baby while you & your husband enjoy the bigger attractions so you can sneak in a few minutes alone.
Your 11 month old can ride any of the attractions where he meets the height requirements (HRs) for attractions. You can find a list of the attractions with HRs by visiting the
Traveling with Little Ones section on the Disney World Website. There you will find a PDF file on the right side of that page that lists attractions at all of the theme parks that have HRs.
Some attractions don't have HRs. You know your son better than anyone, but keep in mind that just because an attraction doesn't have a HR, doesn't mean that every child should ride it. Haunted Mansion is a great example of this - there is no HR but its dark & once you're on, there is no great way to get off of this 7 minute & 30 second ride.
Bring something to help keep him entertained in line - favorite small toys, snacks, bubbles, etc. Be sure to give him breaks from his stroller. Try (it will be hard) to stick to nap times. Take advantage of the Baby Care Centers located in each theme park. Click
here for some tips on strollers.
Let me know if you have any questions about any specific attractions - I'm super happy to assist you. Wishing you many magical memories :-) Allison
