We noticed that Isabella has been more "aware" since the seizure and since she was put on meds. It seems that the only skill she lost (which can happen because of the seizure) is the most recent one she learned, that is sitting with some support from an adult. It looks like her body is still somewhat physically weak from all that brain-wave-bouncing. I believe that there is no reason for her to not regain that skill. It will just take a little bit of time.
A new thing she recently learned is that when she is sleepy she can make herself not fall asleep. While most babies will cry and be fussy-grumpy, my Isabella would smile... even laugh.
Watch this short clip of me rubbing her head to help her fall asleep.
