Walk me through the transition: bottles to sippy w/ meal

So I have been mixing WCM into formula for C for the past few weeks and she is ok with it, but just seems to be losing interest in the bottle altogether - She is offered about 16 oz formula/WCM mixed, and generally has about 12-14 of that. At what point do I stop offering bottles and give her milk with meals? She is a very good eater (knock on wood) but I don't want her to not have any fluids and she isn't super interested in drinking all the time... It just doesn't seem like enough.
