Hi there, Krystal!
Thank you for your question and welcome to the Disney Parks Moms Panel!
How sweet and exciting that you and sister will have a little Princess or Pirate so close together! Just think of the magical birthdays that you can plan for little ones in the future at Walt Disney World!
To skip some of the long lines in the parks, be sure to reserve your
FastPass+ choices before you get to the parks. If you haven't created your
My Disney Experience Account, I would suggest that you do this soon. Also, it's important that you link your tickets to this account so that you can pick your FastPass+ attractions or show. Last, everyone in your party must have a My Disney Experience account, linked tickets, and be friends within this account. It's super easy to do! Check out
this link to see how this is done.
Each day you are allowed 3 initial FastPass+ selections per day, per park. Be sure to check the height restrictions for the attractions. Any attraction that says "Any Height" should be perfect for you and sister and should not present any danger to you and your bundle of joy! I would also suggest to take in plenty of shows! Many of them are inside, with seating, and air conditioning! Just watch for the signage!
Unfortunately, there is no other way to skip the long attraction lines inside the theme parks.
I do hope that you and family enjoy this most magical place during this practically perfect time! Take plenty of pictures and have lots of snacks on hand! You will enjoy showing these pictures to your little ones in the future!
Please visit with us again soon, if you have any more questions!
Happy planning!
