Hi there. My DS will take a smallish bottle of formula now and then, and was happily taking fresh expressed milk up until three weeks ago (when DH went to France for over a week and I went to stay with my parents and stopped expressing). I have a stash of frozen breast milk and decided to use it up in preference to formula for the moment. But DS absolutely refused it and screamed. It dates from 10/10 so only a month old. My DD also used to refuse defrosted breast milk. Does freezing it change the taste? Thanks for any advice!
