Out of no where, she starts to laugh at this game. I am training her arms and try not to let her sit down for long. We do this before her nap, so I can burn out her energy which makes it easy on me. How can she have so much energy? She can recharge in an hour during day time. OMG, she is the reason I lost weight so fast. I don't know how long I can keep up with her, but I will try my best. At least, she doesn't move anywhere now. I can't image us in 6 months or even after she can walk or run... too far, can't image it.
