Help! my lo wants only to Nanny carry!

My lo tends to get cranky and more active at night. Me and my mother try to carry and coax her but she keeps crying. She only stops when the confinement Nanny carries and coax her. She seems to be more attached to the Nanny. It's been 1 week since Nanny's here. What should I do??? Is it bcos the way or carrying isn't as comfy? Or is it that lo used to her smell?? Will she mistaken Nanny as her mother as I don't bf?? Help!!
