I am exclusively breastfeeding my 6 and half month old ds and have just started back at work. The problem is that my ds won't drink my previously frozen ebm. It hasn't gone off and has been stored/defrosted correctly. He has happily drunk previously frozen ebm occassionally for months so I don't know why he won't drink it now. He refused to drink any the other day and dh had to give him a bottle of formula, which he glugged down happily. He will drink it if it's not been frozen. V. annoyed. Got about a litre in the freezer!
