Hey there, April!
Welcome to the Disney Parks Moms Panel. I'm so excited you are planning a trip with your little one to the Most Magical Place on Earth!
Purchasing tickets for adults and children is a breeze online. Just head to the
ticket page, choose a Park Hopper or 1 Park Per Day option, select the number of days for when you will be visiting, then select how many children and adults are in your party. Tickets for kids ages 3-9 are lower in price than adult tickets (ages 10+), but still carry the exact same benefits at the parks. You will be able to add your children to your My Disney Experience account as well as make FastPass+ selections for them.
There are so many fantastic
attractions and entertainment options for preschoolers and toddlers. My three year old son loves the new Slinky Dog Dash attraction in Toy Story Land and all of the kid-friendly Fantasyland attractions in Magic Kingdom Park. He's also equally as happy just cruising around on the various modes of transportation you can find at the Walt Disney World Resort like buses, boats, and the famous Monorail.
I hope this helps, and please return if you have any more questions about planning your practically perfect vacation!
