Greetings Jackie,
Absolutely!
There is no rule that prohibits parents from bringing food and formula into the
Disneyland Park or
Disney California Adventure Park.
As a matter of fact, the Happiest Place on Earth even has
Baby Care Centers available at both parks so that parents have a quiet place to feed their babies, whether you're a nursing mom or simply want a quiet space to give your little one his bottle.
And in case you were to forget something, the Baby Care Centers also sell essential items like baby food, diapers, formula and even baby clothes.
Many families pack their kids' snacks and food items ahead of time and use a
locker rental to store things before meal time. The only thing Disney asks is that you keep your cooler to a 6-pack size container and you're good to go!
Thanks for visiting the Disney Parks Moms Panel.
I hope you have a Magical time during your next visit to the
Disneyland Resort!
