My 14.5 MO DD will drink cows milk from a bottle but not a cup - she was weaned to formula at 7.5 months and then cows milk in her bottles by 13 months. She's currently just having one bottle per day, before bed. I've tried giving it warm, cold, different cups, but she never drinks more than a sip or 2 (but guzzles it from a bottle). At the moment I'm trying to gradually get her used to the taste of it coming from a cup by mixing it with her water - started off with just a splash of milk in her sippy cup of water, and today I got up to about 1/4 milk. Can't say as yet that it will definitely be successful but it's the most success we've had so far!
