Hello Sol,
Greetings from sunny Southern California!
How exciting to know you'll be traveling to the
Disneyland Resort in August!
Hopefully you'll be here in time to catch the
Main Street Electrical Parade, which returned to Disneyland after a 20 year hiatus and will be dimming its lights on August 20.
In terms of bringing your own food to the Parks, the answer is: absolutely!
Although park rules make it clear that outside food is not permitted (aside from light snacks) an exception is made for guests with specific dietary restrictions. In your case, there would be no problem with bringing your own meals, given your daughter's allergies.
I do want to share that the Disneyland Resort is committed to offering a wide range of culinary options to all guests, including those with
special dietary requests. if you arrive at a restaurant or quick-service location and ask to speak to the chef, you will learn that most Disney chefs can substitute different ingredients and accommodate to your daughter's eggs and milk/lactose allergies. Keep that in mind when you're there.
Sending you Faith, Trust and Pixie Dust!
