Meimei trials of Sit-Up
Mei Mei trying to sit up from lying-down position. To be able to sit up assisted at the age of 7 months with a premature history, it's definitely a good milestone. Somehow, probably It's because Mei Mei is smaller in size. That's why she is more agile in a way.
Her movements also looked like a snake - per Mom's description. She curls, twists and turns like nobody's business... Didn't even notice if there's any support at her back.
