Today is already the 4th day she tried sitting on baby walker. She started to feel bored with it. Maybe she is a lazy baby. Lazy to use her leg to "walk" the baby walker. She just used to sleeping comfortably on bouncer or leaning comfortably in my arm when I carry her. So, this time when needs her own effort and energy, she gets lazy.
When I video recording her this afternoon for about 1 min, she just stayed on the same position, without moving a step!
