I've been trying to get my 5 month old DD to take two bottles of formula a day instead of breast ready for my return to work in two weeks, she will now take some after much battling but only takes 3/4oz at each feed. She is weaning nicely onto solids. I'm convinced she holds out for her bf later in day and am worried now about whether to switch to formula or keep persisting . I really don't want to give up breast if poss and expressing not option. Any advice gratefully received.
