How many ounces of cows milk does your LO have in a day? I figure she's probably getting around 10 ounces of Breastmilk per day from our nursing sessions. How much cows milk should I aim to get in her during the times she's at day care? When she was all Breastmilk she was drinking 12 ounces in the time she was at school. We are transitioning right now so she gets a cow's milk/Breastmilk mix. But she's starting to not finish it all because she's eating so much more table food. I'm thinking I'll go to two 5 ounce servings rather than three four ounce servings. Thoughts?
