Today I didn't give Kyle and Emily any milk with lunch (which is normal). When it came time for their afternoon bottle, I gave them each a sippy cup with 3oz of whole milk and 5 oz of breast milk. Emily sucked it right down. Kyle threw a fit at first because he wanted a bottle, but eventually he drank it all!
I think I am going to stick with this for a couple days and once both of the toddles are doing well with it, I'll start to give them a little less breast milk and a little more whole milk.
Once they are drinking only whole milk in the afternoon, then we'll start to work on either their morning or night time bottle. I haven't decided yet which of those will be the first to go.
