Hiya Megan!
Welcome to planDisney! Traveling with a child under 2 years old to Walt Disney World is one of my favorite things as they are free! There is nothing like seeing the wonder and excitement in your baby's eyes as they see their favorite characters and experience the magic of a Disney day.
Now, to get all the features of your
MagicBand+ you have to
link it to a My Disney Experience Account but that includes features like accessing Parks, tapping into a Lightning Lane entrance, and if staying on-site making payments at merchandise and food and beverage locations. Your little 2-year-old won't need to do all that and probably just wants to see it light up and vibrate! Now, to make that possible for them, make sure to have them linked to your
Family & Friends list. Since your little one is under the age of 13 they can't make their own account but you can add a guest with their name and information. The fun part that my children love is picking out their character icons. I'm currently Ariel as I wish I was a mermaid princess. Who wouldn't?!
I did confirm this with a Cast Member who stated that even without linking to a My Disney Experience account, as long as they are on your Family & Friends list and connected to your Plans they should experience the haptics and special light patterns. Just make sure the MagicBand+ is fully charged!
Both the Cast Member I spoke with and I had the same worries about a little one with a MagicBand+. It could get lost on their little arms! Now, there is a way to remove part of the band and make it fit more tightly to smaller wrists but I must admit even with this feature it's a bit bulky and large. My children at that age tolerated it for a few minutes at a time. My advice is to secure it to their wrist with a rubber band looped over to make sure it doesn't fall off. Another idea is to do what I do and wear it yourself until something magical happens and then hand it over to the little one for those special moments.
I do hope this helps and that you have a magical time with your little one when you arrive!
Happy Planning!
