Vacuum cleaner is hands-down the best household appliance. It picks up dirt and dust blah blah blah, but most importantly, it puts crying babies right to sleep. I have heard it many times, but didn't believe it. Today we tried it on Eli. As soon as we turned it on, boom! He's out. The problem is he wakes up as soon as we turned it off. It's funny to see him freeze whenever we turn the vacuum back on. They should make mobiles or baby CDs that play vacuum sound.
