A great thing, and something of concern

I recently cracked the code on being able to make Beatrice stop crying at any time within 20-30 seconds. It involves laying her across my thighs and bouncing my feet up and down ever so slightly very, very fast. No matter how hard she was crying it is like she just sat down in one of those vibrating chairs like they have at the mall or Sharper Image (RIP).

Here is Bea in mid vibrate:

My one concern about this is that it makes my legs tired, and that at some point when she weighs about 45 pounds this isn't going to be so fun.
