I would do the wi/wo. So if she's up at night & crying then you go to her & tell her its night time, etc..., leave & start counting. If she's still crying at the end of your count then you go bacl to tell her its night time (maybe rub her back or something reassuring), leave & count again. If she's not crying at the end of your count then you don't go in.
Good luck... consistency pays off when sleep training so if you at some point decide you can't handle it & she's crying too hard, rather than giving her a bottle (& confuse her even more) you could try spend more time soothing her (no rocking or anything... but rubbing back & saying soothing words "its ok, your tired, go to sleep"). Remember that you are not making her cry. You are helping her learn something new & she'll be crying because she won't understand what you want of her.... up until now she thinks she
needs a bottle to get back to sleep so you are teaching her otherwise
Will be waiting for your reply
