Hi F.,
I may not be the right person to respond here since I nursed my 1st son for 23 months and my 2nd for 30 months... but, maybe you could pump and still give her your milk? And maybe you could try putting something that tastes bad, like vinegar?, on yourself before she nurses each time. That might deter her from you and still give her your milk in a bottle... a taste she is familiar with. Then you could slowly wean her from your milk altogether. I don't know... just a thought.
