Transitioning from demand feeding to bottle & nanny care?

vszapp

DD feeds on demand right now - every 1.5-3.5 hours during the day. I have tried pumping and know she'll take a bottle, but I am worried that it will be a tough transition from nursing to bottles from the nanny when I go back to work in 3 weeks. I think she does a lot of comfort nursing at the end of a feeding, and it really helps to calm her before a nap.She won't take a paci, so that's out. Any tips on making this transition?
