Hi Krystal, welcome to planDisney!
Thanks for bringing your question to us, I can certainly help!
Regarding strollers, I just took a look at the
Disneyland Resort's stroller guidelines, and two key points I want to mention are that strollers larger than 31" x 52" and wagons are not permitted. Strollers wagons are also not permitted. And just so you know, you do have the option to
rent a stroller at the
Disneyland Resort!
Next on to diaper bags! I looked over the
Disneyland Resort Rules, and while I didn't see anything specific on diaper bags, there are a few key items that I would like to point out. Suitcases, bags, coolers, or backpacks, with or without wheels, larger than 24" long x 15" wide x 18" high are not allowed. So just make sure your diaper bag is within those guidelines. In addition, I do want to mention that all bags may be subject to screening and security checks.
OH! And before I let you go, I do want to highlight the amazing
Baby Care Centers! When our kids were babies, we would visit the baby care centers constantly! They offer a clean and comfortable facility with changing rooms, nursing rooms, a feeding area with high chairs, and more. At
Disneyland Park, it's located at the end of
Main Street, U.S.A., next to
First Aid. At
Disney California Adventure Park, the baby care center is located next to
Ghirardelli Soda Fountain and Chocolate Shop, across from
The Bakery Tour in Pacific Wharf.
I hope that helps, but if you have any more questions, please do visit us again!
See ya real soon!
