I have had a REALLY hard time losing the weight after baby #4.  Finally, in September, 9 months after giving birth, I joined Weight Watchers.  I've been doing really well.  I've lost about 14lbs (I still have 25 to go).  Today, we were doing science, and talking about gravity.  The science book said: "Weight is how much of a pull gravity has on something."  I joked, oh, I don't really have a lot of weight to lose, I just have gravity pulling on me.  Bubby said, "Boy, Mommy, you sure have A LOT of gravity pulling on you!"
