MY LO is coming up to 11 months and is on 3 bottles a day and what I do is offer 1 bottle in a cup per day, generally the mid afternoon bottle of 5/6oz not everyday though.
Over the next few weeks, I plan to also offer her morning bottle in the cup too. Does your LO drink water/juice from a cup? If so, taking the milk from a cup shouldnt be a problem...maybe just start offering her half her milk in the cup, the rest in the bottle so your not doing it all at once x
