I'm going back to work next week and dd has been bf since birth, I'm still doing 4 feeds a day at the moment. When I do go back I will be able to do the morning feed and the dream feed, I haven't been able to express so she'll have to have a bottle of formula at bedtime, but I usually give her a feed midafternoon too. Would it be really terrible if that was a cup of cow's milk? She's 9 and a half months old.
