Of pacifier and frozen milk

My baby dislikes the pacifier and prefers her thumb and forefinger a million times more! She always ditch the pacifier that I insert into her mouth and puts her thumb AND forefinger into her mouth instead!

I have many bags of milk in the freezer... but now my baby only wants fresh milk...

I always latch her when I'm with her but at times when I'm not around, I'll have to pump in the morning (when I wake up engorged and can get over 100 ml per side) and keep my milk in the fridge for my mother-in-law or hubby to bottle feed her when I'm out. She totally rejects the frozen milk so I'm at a lost of what to do with the 20+ bags of milk in the freezer!
