Hi Gertie,
Thank you so much for visiting the Disney Parks Moms Panel with your question. We on the panel love helping guests to plan magical vacations!
Yes, your infant is more than welcome to visit Walt Disney World with you! When my daughter was a baby, we took her to Walt Disney World as well. One of my favorite tips for guests with infants is to be sure to take advantage of the
Baby Care Centers. These are located at all four of the Walt Disney World theme parks, and offer a great spot to change or feed your little one, or just to take an air-conditioned break if you or your baby needs one!
I also enjoyed taking my daughter on gentle attractions or into shows when she was a baby at Walt Disney World. At
Magic Kingdom, slow-moving attractions such as it's a small world and Under the Sea - Journey of the Little Mermaid are great for the littlest ones. At
Disney's Hollywood Studios, you can head to shows such as Beauty and the Beast - Live on Stage and Disney Junior - Live on Stage!.
I hope that these thoughts are helpful for you, Gertie. Please do let us know if you have any further questions.
