We went to cows milk with our daughter at one. We did it slowly by adding some to her formula. This way she got used to the taste too. slowly we just added less formula and more milk till it was just milk. Worked for us.
My daughter did get a a little ezcma from it and my dr told me there is an immunologist who believes that something in the heat treating of milk for the uht milk in supermarkets makes it less allergenic for stuff like that so we switched andit worked. its not proven but worth a shot and this way you always have some spare in the cupboard smile
