Hello Shannon! Thank you for coming back to planDisney with another great question. How exciting that your trip is just a few weeks away!
I highly recommend bringing a
stroller for your little Mouseketeers, even if you think they may not need one. Tons of walking around the parks can be very tiring for their little legs! There are definitely stroller parking areas throughout both
Disneyland Park and
Disney California Adventure Park. You'll usually see a cluster of strollers parked together, and most likely there is a helpful Cast Member nearby if you need assistance or have a question on where to park your stroller. A quick tip I'll share is that sometimes Cast Members need to relocate strollers from time to time, so if you are searching for it after you've ridden an attraction and it's not in the original spot, do not worry! Most likely it has moved to a nearby location, and a Cast Member will be able to point out where the new location is.
For diaper bags, you can always leave it with your stroller, I would just remove any valuables from it while you ride an attraction. There are also
lockers available to rent in each theme park, as well as outside the Main Entrances to each park in The Esplanade accessible from the
Downtown Disney District.
If you are ever in need of a quiet place to change a diaper or need some essentials for taking care of your little ones, I highly recommend stopping by the
Baby Care Centers located in each park. It's a great place to take a break, get out of the heat, and feed or change your infant or toddler. The Cast Members there are always so friendly and helpful, it's such a wonderful amenity for your long park days!
I hope this information is helpful for you Shannon! If you think of any other questions for your trip, please
come back and ask!
Have a magical trip!
