Hi
I'd probably try to get her to sleep on her back in the pram during the day. Try to make her lie flat on her back (ie. not in a seated position), possibly with her head raised slightly.
Then go for a walk with the pram and see if she'll settle like that. It'll get her used to sleeping on her back.
I sometimes let my little boy cry for a LITTLE, and then he goes to sleep. This is only about 20- 30 seconds max, if he cries any longer, I pick him up. Depends on the cry too, I often pick him up straight away.
Many babies prefer sleeping on their bellies when they're little, but she might change when she gets a few months older.
Also, if the pram thing doesn't work, get one of the monitors mentioned in this thread, because you really need to sleep, or you'll completely loose it!
A happy mum makes a happy baby!
Hope it works out for you
Christine
