afternoon all, want to try getting DS (10 months) off the bottle. He quite happily drinks his water with lunch tea etc from the tommee tippee flip lid cup, but I know they are supposed to have a minimum of 18 fl oz of formula a day until 1 year old. He would never drink 7/8 oz from a cup. Is this usual? Any suggestions? Leave him until 1 with the bottle then transfer when on cow's milk?
