It can happen. During December Walt Disney World is crowded and people bump into each other, people trip over strollers, people step on other people's hands, etc, etc and oh my gosh etc.

Since everyone carries a bag of some sort into the park, like the Disney Prince Daddy featured above wearing a backpack, always have a first aid kit on hand for the minor Trips, Boo Boos and Ouchies. A trip to the first aid building in each park may take a good while, depending where you're at in the park.

The important thing is to not get upset and argue with each other and to just both give your child/niece/nephew or little brother/little sister all your helpful hands making sure the rest of his/her day will go back to a magical day, an expensive yet magical one.
