Hi Lori,
Taking your young children to Walt Disney World for the first time is so magical! I remember taking my daughter when she was younger. Seeing the parks anew through her eyes was wonderful.
I love your choice of parks to visit with your children. There are so many attractions for little ones at both parks! When she was smaller, our daughter loved it's a small world and Peter Pan's Flight at Magic Kingdom. She also enjoyed Journey into Imagination with Figment and Living with the Land at Epcot. Even though some of the information in Living with the Land may be too advanced for your little ones, they will probably enjoy floating along in the boat and looking at the plants.
Since each family is different, I do suggest that you order the
free Walt Disney World planning DVD. Watching this will give you some ideas for attractions that your family might enjoy. The, I also suggest ordering free
customized Walt Disney World theme park maps. This will allow you to choose attractions that you think your little ones will enjoy, have them put on maps and delivered to your door!
One more thought for you. With children as little as yours, you might find the need to take a break during your theme park day, or may need a place to quietly feed your baby. Be sure to take advantage of the
Baby Care Centers at the theme parks. They offer a quiet place to take a break, change the baby, and pick up any supplies that you might have forgotten.
I would love to help you plan you magical vacation further, Lori; however, I am limited in the amount of space that I have to answer. Please do not hesitate to ask if you have any further questions!
