It is hard. My son would end up sleeping with us but it was never intentional.
Try putting a shirt that you have worn (a wee bit smelly is good in this situation
the fitted crib sheet. When she lays on it, she will warm it up and the smell of you will be close.
I would suggest standing beside her and soothing her with back rubs and such, and help her fall asleep.
If it really doesn't seem to work the greatest and you are able, try moving the crib into your room.
And for us, putting the crib mattress on an angle worked. I was thinking about that the other day and wonder if that is because when he slept with us our weight would naturally make the mattress angled under him?
Most of all, I have found lots of research when my son was young and I last looked at this to suggest that your physician isn't just trying to fed you a line, she really won't be hungry. Likely lonely or bored!
