Stair Steps?

Foofie is eager to reach the 40 lb. mark so that she can transition out of a car seat into a booster chair.  After church we checked her weight, as well as the weights of a few other tagalongs.  Here’s what we found.

Ruth: 34 lbs.
Robyn: 31 lbs.
Henry: 28 lbs.

Does this mean that my cooking is getting better?  Or maybe it means that they are wising up to it as they get older!  ;-)
