Hello Breanna, and welcome to planDisney! You'll be visiting the "Happiest Place on Earth" in just a few short months, how exciting!
You can absolutely bring a stroller inside both
Disneyland Park and
Disney California Adventure Park. Even if you think your little Mouseketeer won't need a stroller, I'd always bring one just in case since it is a ton of walking for those little feet!
If you're in need of a
stroller rental, they are available to rent at the
Disneyland Resort just outside of the theme parks near the Disneyland Park main entrance. Both single and double strollers are available to rent.
You'll find that a lot of the guest strollers look very similar, and I recommend tying a brightly colored ribbon to the handle to help you easily identify it. I'd also try to bring a stroller rain cover if the forecast calls for rain, there is nothing worse than a wet stroller!
I hope this information was helpful for your trip planning Breanna, and please do not hesitate to come back to planDisney and
ask me any other questions, we are here to help!
Have a magical day!
Melissa
