I've been diligently expressing my milk for DD to have when I'm at work. The milk was defrosted in readiness for her. The trouble is, she refused it all day yesterday during my first day back to work. Today, I've had a taste of today & it tastes foul! It was frozen within a couple of days & is only 3 weeks old. It tastes sour & I can understand why she didn't want it. She happily takes it unfrozen, IYSWIM.
Has anyone else had this problem & does anyone know why it tastes different??
