Sitting - not for the faint of heart

She is 6 months old... and change. :( Mommy is not handling the aging of the baby well. Her latest trick? Trying to tripod and sit up. She does baby crunches a lot. She can sit up for approximately a millionth of a second before toppling. Or she bends so far over her little forehead nearly touches the floor. Cue the spit up!
