Hey there, Erika!
Welcome to the Disney Parks Moms Panel, and thanks so much for your great question. The Disneyland Resort is so accommodating to families with children of all ages. You and your infant are going to make such magical memories together.
I'm delighted to tell you that you are more than welcome to bring a small cooler for bottles inside the Disneyland Resort. Just check out the
Park Rules before arriving to clarify exactly what is permitted inside the parks. When packing your tiny cooler, you will want to use a reusable ice pack since loose ice in coolers is not allowed. When my son was an infant, I brought a small soft-sided cooler that fit four bottles and a blue reusable ice pack, and it was perfect. I also suggest utilizing the convenient
locker rentals inside the parks so you don't have to carry everything with you all day. These are also great places to store a breast pump, extra clothes for your little one, or souvenirs you purchase throughout the day. I love that you can access your locker as often as you wish for just one low price all day.
Did you know that there are also
Baby Care Centers located in each park? These make a wonderful place to warm bottles, feed, pump, or change your little one. When your tot is a little older they can even use child-size toilets here when potty training. My son loves them! You can even purchase infant essentials you need during your trip here as well.
I hope this helps, and I wish you a trip that is practically perfect in every way!
