Trying to get DD on to a bottle (only for one feed a day - not giving up bf just yet). She is nearly 6 months and has been exclusively breastfed, though have been trying to get her to take a bottle for a month. She absolutely refuses, 'cept for chewing and playing with the teat and the most she has ever taken is an ounce. Lots of friends have suggested going straight to a cup - but how does this work and which cups are best? Also how do you ensure they get enough?
