Well it has to be done at some point, otherwise the kid will be getting home from university wanting to suckle
It is simple..... just stop. Eventually the baby gets hungry enough to eat anything. Job done. Too many people let the baby control what happens, when all the parents need to do is make a decision and stick to it.
Also, switch to a natural teat on bottles
