My son is almost 8weeks and I have always given fresh breast milk, today for the first time he will be staying...overnight at my mothers because we have an obligation out of town for the night. My highschool reunion. I defrosted for stored breast milk for the first time.....it smelled different than fresh milk, but not rancid...perhaps a little soapy. He took it fine, infact cried when I removed the bottle to burp him. It tasted a little weird but not bad and definatley not rancid, maybe a little soapy or floral tasting. The milk I gave him today was from 10/31 so almost a month in the freezer. If I did have and issue would he still take it? and if he did take it inspite of a lipase issue is it safe?
