You probably have been organizing all the details of your trip for months, going through moments of worry and anxiety, but the children should not go through such a long waiting period.
Organize everything in secret and tell the little ones closer to the day of departure so they won’t be so unquiet and asking questions every and all day, which is normal for their age.
Tell them about the Disney world, all the magic that surrounds this universe and all the attractions you will visit. If you already know that your child will not be able to play on rides that require a minimum height, comment with them so they do not create false expectations during the trip. Learn more about the attractions you child may ride here, according to their height.
It is important for the child to know what to expect in the parks and have a script of what she can and cannot do, so she travels with these ideas and enjoy the trip much more, getting to know her favorite characters and playing in the appropriate attractions for her age.
