Hi Chris,
You'll find that Disney World is a super friendly place for even the littlest Mouseketeers.
You will be allowed to bring your daughter into the shows. She may be entertained by the music, movements and bright colors in many of the shows. If she becomes upset, you will be allowed to take her out. Typically you exit the doors opposite of where you enter. If you have any questions, there are Cast Members located at the entrances and exits that can assist you. I think that you'll find that there will be a lot of understanding guests so if she becomes upset, feel free to take her out.
You are welcome to hold her on your lap on any the attractions where she meets the height requirements (HRs). 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.
Bring something to help keep her entertained in line - favorite small toys, snacks, bubbles, etc. You can also play games like peek-a-boo. Be sure to give her breaks from the stroller. Try (it will be hard) to stick to nap and feeding schedules.
Baby Care Centers located in each theme park provide an awesome place to feed and change the little ones during their visits. Click
here for some tips on strollers.
Let us know if you have any other questions during your planning. We're super happy to assist you.
Wishing you minnie magical memories :-) Allison
