Hi,
I had the same problems with my 2 youngest children, now 8 (son) and 2 1/2 (daughter) years old.
My son didn't like the taste of whole milk, so my pediatrician suggested soy milk, for a couple months, then gradually switch to whole milk (half soy/half whole milk).
It worked, so I tried it again with my next child (and my last). She drank soy milk for about a year. Now that she is on whole milk again, she still does not like it much, but I cheat and I dont know how appropriate it is, but I ad about 1 - 2 teaspoons of flavored coffee creamer to her whole milk, then warm it, when I put it in her nap-time cuppy(I have also used chocolate and strawberry, very little, just enough to add a little flavor).
She drinks out of a cup during the day, and has a 8 oz cuppy that she drinks just before she goes down for a nap, and has a water cuppy with her in case she gets thursty during the night.
At a year old, you may want to try introducing a cuppy, with breast milk, or try the soy. But, if you are planning on weaning soon, now would be the time to make that change to soy or whole milk in a cuppy instead of a bottle.
good luck
