Hi, i tried to thaw my breastmilk which has been frozen for 1.5 months and find that it has a bad smell... did not dare to give it to my baby and ended up throwing it away.. previously i have given my baby frozen breastmilk but those were less than 1 month old... read that frozen milk should be able to last at least 3 months in the freezer... anyone encounter this problem before?

i tried to thaw another batch which are quite recent and it did not smell as bad... does it mean that the frozen milk that are stored longer will smell more worse than those stored recently?

pls advise..
