Re: whole milk now nursing less???
As long as your LO is nursing somewhere in the neighborhood of 3-5 times a day, you don't need to introduce cow's milk. But you don't need to be afraid to do so, either. In your shoes, I'd offer it as a beverage choice. But I wouldn't be amazed if she didn't take to it- my older kid didn't drink cow's milk until nearly 5, when she discovered just how tasty it is when cookies are dunked in it!
Coolest thing my big girl said recently: "How can you tell the world is moving when you are standing on it?"
Coolest thing my little girl sang recently: "I love dat one-two pupples!"
