A: For the first three months the bones of the hip and pelvis protect the baby. During this time it's very difficult to hurt the baby. Once the baby pops up above these bones, it's vulnerable to injury from falls and trauma.

Gentle amusement park rises are permissible. However, rides that throw you around or make sudden rapid stops can be hazardous to the baby. I suggest that you enjoy your trip, but abide by the warnings posted on the rides—and make sure to take loads of photos of your children as they delight in the fun of Disney World.
