Breastfeeding

So my baby is turning one this month and my goal was to breastfeed for a year. My pediatrician gave me the okay to start introducing her to regular milk. I have been doing half and half with soy milk and breastmilk. I also have a good amount in my freezer stash. I reduced my pumping to 3 times a day. Any tips on how to stop pumping and have your milk dry up ? Im proud of myself for lasting a year Im ready to be done though 😂
