pulling up in crib - wont sleep

my 7 1/2 month just has so much fun pulling-up in her crib and does not want to fall asleep.  she will cry for help every couple of minutes because she cant get down, so i lie her down again and walk away.  well, this goes on for about an hour until she finally falls asleep, or until i decide to breastfeed or bottle her to sleep. then of course i wonder if she was just hungry the whole time...tho in the previous 2-3 hours she's had a breastfeed, a bottle, a meal, and a breastfeed again before sleep. she is very good at self soothing so i almost always put her down while she is still awake (and of course quite sleepy). But i'm wondering if, for this stage, i should just try to nurse her to sleep or something? or should i give her that bottle before her nap (rather than interrupting naptime/pull-up-time to finally feed it) to ensure she isn't hungry, then just repeatedly lie her down after pulling-up until she tires herself out? any thoughts?  maybe wait until she is more tired before nap?  i'm fairly certain that she is tired enough and her tummy is full enough for sleep, but since she's developed this new fun skill, she just wants to play instead! cute little thing  i'm sure somebody out there has experience with this! haha.
