Like one poster suggested.. mix regular milk and formula and slowly increase the quantity of milk. this worked great for my son. my daughter switched to milk without the mixing of formula and milk. the sippy cup.. start using that at every feeding. start out with that and then you can switch to a bottle later in the feeding. but always start with the cup. after a few weeks, just dont give the bottle at all. my daughter was very stubborn about using the sippy cup but i just kept on with it and it wasnt very long before she stopped taking the bottle.
good luck.
