My ped has been after me since my DD2 turned one to get rid of her bottle (she's 18 months now). With my older DD, we stopped after she was 2 and she never touched milk again until she was over 3!
How do I do it? Did you phase it out? Or stop slowly? She has bottles when she first wakes up, after her nap and before bed. She loves it. She also does not drink milk if it's in another cup.
