Your vocabulary has been expanding quite a bit lately, and you have definitely been trying to sound out words. You can follow along most of the alphabet and numbers, sounding them out, but your current favourite words ( at least for tonight ) were "UP, momma" and "DOWN, momma".
And as if to make sure that we knew that YOU knew those words, you were throwing your arms UP when you said "UP!" and bringing them back down when you said "DOWN!".
You also gave your poor dad a fright when you demonstrated your comprehension of the words by climbing UP onto momma's study chair, and then standing up in the chair while going "UP!" , and then crouching down while saying "DOWN!". Over and Over.
THAT activity didn't last very long, to say the least. :)
