Baby only wants confinement nanny

Hi mummies, I need advise and help here. These couple of days, my 7 weeks LO has been very attached to the confinement nanny that she cries and yell in the evening and night whenever we carry her to sleep / bottle feed her. Baby stops crying as soon as the confinement nanny carries her. This is very depressing for both my hubs and I. We have been spending a lot of time with her throughout the day to create the bond. Only these few days baby doesn’t want us evening onwards. Any advise what can we do pls?
