Weaning breastfeeding

Mamas my daughter has been EBF since day one. She now only gets it for naps and at night. She has not slept through the night yet and my period has not returned yet since having her. My husband and I would like to try for our second within the next 6 months. I need help on how to stop breastfeeding so that it’s easy on both of us. She is also not a good eater. She gets plenty of fluids but most of the time even pushes her sippy cup away. Any advice on how I can stop breastfeeding?
