It's natural that a child's baby walks result in falls. Though the child may cry, it will start doing the same in a few seconds. The fall doesn't embarrass the child.
But what will happen if a model performing the catwalk falls? She won't cry, but she will surely be embarrassed. It gives a good photo opportunity to the lensmen too.
Here are a few pictures of the models falling.
