My DS is a few days off 11 months. I am going back to work next week for just a day a week and my little boy is BF. He has never taken a bottle and the time I tried him with formula in a cup he spat it out and refused the cup. The cows milk is just to have during the day for mid morning/afternoon and I can BF him first thing and before bed. He drinks water happily from a cup. What would you do?
