Hi, there!
Aimee, I am so happy to answer your question. I have a four-month old too, and I think your idea is just the cutest!
Characters at the Walt Disney World Resort have signed all sorts of things that Guests have brought with them to meet-and-greets, so I am sure you will have no problem getting some of your favorite characters' autographs on your son's Mickey Ears. Since the Mickey Ears are baby-sized, I would suggest prioritizing the autographs you want the most and aim to have three or four of them signed on the hat. Take along the picture mat for additional autographs you'd like to collect. Then, you can display the Mickey Ears and the picture mat together with an adorable photo of your son at the "Most Magical Place on Earth!" Don't forget to take a few retractable Sharpie markers with you!
My family's favorite location for meeting
Mickey Mouse is at Town Square Theater in Magic Kingdom Park. We have the most precious picture of our infant son meeting Mickey Mouse there for the first time. It makes us grin ear to ear every time we see it!
Did you know there are conveniently located
Baby Care Centers in each of the four Walt Disney World Resort theme parks? The Baby Care Centers have everything you and your son might need, including a private nursing room, changing room and on-site shop where you can purchase baby essentials like diapers and wipes.
Aimee, I'm so excited for you and your family to enjoy the magic of the Walt Disney World Resort with your son!
