That is all normal. Every thing you just described my mom did the same exact things. She might not remember who you are sometimes but Don't get discouraged, the brain has to heel. Keep talking to her, but not to much, let her rest. It took my mother four months to start talking, but she gets tired somtimes. She laughs and makes jokes. Remember this. Everyone is different, and you don't know how long it's going to take for them to get better. It can be a year or more. You have to be positive around her and make her laugh. Laughter is always good.
