Hi
DS is doing this too. What I do is bath, bottle, cuddle, then I pat his back (really quite firmly) then put him into the crib. Sometimes he's fine and I leave, sometimes we do pu/pd (he gets overstimulated if I try to soothe him in the crib though he is 10 months). When I leave the room I keep an ear open for him. He often will mantra cry for a minute, then he gets really quiet. Then he screeches. I go in and he's standing. We do the whole thing over and over again until he's ready to fall asleep.
I say do what works for you. If she stays quiet and falls asleep with you in the room, then do it. If you don't mind going in over and over to put her back down, then go with that.
HTH
