Hi, Megan. Congratulations on your new little one! I packed enough diapers for a diaper change every hour I was at the parks - so if I planned an eight hour day, I packed eight diapers. For me, I preferred having a full size box of wipes instead of the travel packs. I always seemed to run out of wipes in the travel pack just when we had a diaper emergency! I carried a box of disposable bibs, so I didn't have to worry about storing a soaking wet bib all day. You may want to keep two full outfit changes with you as well, in case you have an emergency.
If you are not breast feeding, find out if you can get your formula in the single serve powder packets. They were so easy to use, so convenient - just add water and shake, and really easy to carry. To minimize bottle clean up, I always used disposable liners with my bottles.
Even if the weather is cool, the Florida sun can be brutal on baby's tender skin. Bring a hat and sunglasses for the baby, and keep a light weight receiving blanket or two handy for extra shade or for inside an air conditioned attraction.
Don't worry if you get to the parks and realize you forgot something! Pretty much everything you need will be available at the Baby Care Centers, located in each of the theme parks. You can find out where they are located by going
