I'm not sure that I would be cutting back like that so much as bub still needs to be getting the calcium / iron from somewhere...

When we put Zander onto cow's milk we did it slowly. He had a milk bottle in the morning then the other 2 bottles of a day were formula, for about 2 weeks. Then we went to milk for 2 bottles a day & formula for the night bottle for another 2 weeks, then finally onto 3 milk bottles a day.

I have also heard of mixing in 1/2 to 1 scoop of formula into the cows milk so that the familiar taste is there.....
