I've just started going to work and have a freezer full of frozen BM for feeding her during the day whilst I'm at work. However, my helper has told me that my 4-month old does not like the thawed frozen BM and is not drinking it. Does the taste of the BM change after being frozen and thawed? Does anyone have similar experience and can tell me what I can do about it to get her to finish the supply of frozen BM? I don't want to throw out the BM and feed her formula instead.
