Gosh that is insane. How can you stop constant waking and her reliance on you? I guess that depends on what you are willing to change. Do you want to keep feeding overnight? Do you want to keep co sleeping? Do you want to be able to settle her without resorting to bf'ing? Do you want to introduce solids? I'm not suggesting any of these things are wrong, just that the combination of these things doesn't seem to be working for your child.

Any or all of those things could contribute to frequent night waking. all babies will learn to sleep through the night eventually but if you want to change this behavioural pattern (assuming there is no medical or developmental reason for frequent waking) then you need to change something about what you are currently doing in order to change your daughters night time behaviour.
