This is the second day that we have tried whole milk. I am only trying it for her breakfast & morning nap. For breakfast I give her cold whole milk- she takes a couple of sips but then she's done. Not very fond of it. Then I tried giving her warm half breast milk half whole milk for her nap- she wants nothing to do with this! I thought because it is warm and she can taste a little breast milk that she would like it a little more. Any tips? It's only day2 so I know I need to give it a little more time.
