Labor can get messy.
If you, like me, are the kind of person who would rather clean out mystery, slime-filled Tupperware from the back of the fridge than watch anything childbirth-related, you may have skipped all of the videos detailing exactly what happens to your nether regions when a baby is making its entrance.
The only problem with this is, for some, visualizing what your body is doing can give you a greater sense of what you need to do to help make it happen.
Using a balloon and a Ping-Pong ball, this video brilliantly describes the difference between Braxton Hicks contractions, and the real deal ones that actually thin and dilate the cervix.
No blood, no gore, and a fair amount of suspense while you wait to see what the Ping-Pong ball does. I give it two thumbs up.
