Baby sitting when supposed to sleep


So when my daughter (almost 9mths) does not want to go to sleep, she pushes into sitting up. She especially does this when it’s nap time lately. Is there nothing I can do but continue to go in their and lay her back down? I totally know she needs a snooze right now, but I have been in there 6-7 times already and each time she pops back up before I even get out of the room. Do I just leave her in there for ‘quiet time’? Maybe she’ll lay down on her own?
