They took her to lunch at Crepe Myrtle:
...and Aunt Tammy bought her her first pool! Margaux is now a big fan of the swimming pool. She just looks at it and says "water" with a sort of awed tone in her voice, as in "that's a lot of water!"
She likes to sit and splash both herself and everyone around her.
And this pic is actually from the previous week when we were in Fort Worth. Neiman-Marcus has a small children's section with (what else) a toy Ferrari. Margaux just hopped right in like she belonged there.
And here is a pic of Tammy reviewing parts of the foot (metatarsals, proximal and digital phalanxes, etc.) with Margaux.
