1. Step into the bathroom. Close the door.
2. Make or receive a phone call.
3. Use a loud appliance, such as a vacuum, hair-dryer, or blender.
5. Close your eyes for longer than a blink.
(If these all fail, try to lay down with your baby to put them to sleep. Just as you are about to get up and leave the finally sleeping baby, someone will call out "Mooommmm??!!!")
