Parenting tip #4123.......

If you're sitting on a couch playing with a baby on your lap and you suddenly feel a wet spot near your groin and know for a fact that you aren't wetting your pants, it's pretty likely that the baby's diaper has sprung a leak and she's actively wetting herself.

Solution: Make a face indicating your dislike of the situation, lift up the baby and run to the nearest diaper changing table in the house.
