Hey gorgeous every bub is different and they all go through these stages but some of the things i was always told to try were:

* Make sure the room is REALLY dark
* Try putting on some soft music, maybe she sleeps on in the bouncer as there is noise around
* Try putting the bouncer IN her cot and see how she goes, then as she settles a little more herself in the bouncer remove it and try patting etc in the cot.

I am sure it will just be a stage, just take it 1 sleep at a time and try a few different things and go with what works for you for now, if her sleeping in the bouncer isn't a MAJOR hassle then go with it, just try the cot, if it doesn't work go with what does.

hun your doing a fabulous job!
