After much delay, we finally got Mira's Kidcart up and running again. Pushing her around in a stroller over the past few weeks has been a hassle, but we survived. The seating company rep came over this afternoon to install the cable and to give an assessment on Mira's bed situation, so we were able to get everything accomplished in one day.
Mira's crabbiness has subsided somehwat over the past few days. Perhaps it is her system getting acclimated to the Depakote and/or the fact that she is eating a little better these days.
I thought I would post some video of Mira sitting up again - this one is pretty amazing. After venting some frustration, she managed to maintain some balance once she was up for about 20 seconds! I thought she was going to a faceplant at first, but she kept right on bouncing around. Go Mira!
