Sienna is the ONLY one that can make Mags laugh. I tried all day long with no success. She's immune to tickling, raspberries, silly faces, and peek a boo. I've attempted everything, but alas it was all in vain. I sat her down and walked away defeated to do the dishes and the next thing I hear is Miss Maggie laughing her head off. I turned around and all Sienna was doing was standing there sticking out her tongue. Sienna looked at me and said, "See mom, it's not hard." Punk.
