M.S.
Hi L.
My son is almost 11 months and when he learned to sit and stand, we had the same problem. Basically, when they reach a new milestone you kind of have to reteach them to go back to sleep. As I have seen with my son, the excitment of this new mileston will die down in a bit. Let her do all of it during the day so that she can get it out of her system (standing, sitting, etc). Now, she'll still do it when you put her in her crib but it will be one or two times and then they pass out.
Stop taking her out of the crib (if you are). What worked for us is to put him down and he would (and still sometimes does) giggle and stand up. We wait a couple of minutes (5 or 10) go back in and lay him down and say Goodnight, it's bedtime. Don't look back when you are leaving the room or they think it's becoming a game. You might have to do this a couple times but by the end of the week, it should get better. If she's waking up in the middle of the night nad standing and/or sitting, do the same thing. DOn't take her out of the crib, put her down say goodnight and leave without looking back.
Good luck!
