My lo is 6mth old and iam trying to stop bf. He has had occasional formula before without problem. I have been trying to give 1 bottle a day. But he has been sick quite a bit after ff. Is this normal?. Also it says on formula tin 5 X 7oz feed in 24hr so I have been trying to give 7oz feed but he cant finish it. Would love to hear from other bf mums who have switched to formula -have u had similar problems?
