Help! Quickest way to get my daughter to stop breastfeeding?

Just found out I’m pregnant and need to ween my daughter off the boob as fast as possible. She is about to be 18 months old. She nurses twice through the day and at night to fall asleep and randomly through the night. Suggestions would be much appreciated 🙂
