Best way to wean my baby off the breast?

Ava

Hi mamas. Need some advice. I'm still breastfeeding my 16 month old, and loving every moment. I need to stop soon though as I'm on my second trimester with my second and I'm so paranoid about him kicking me at night. He's been on solids since 6 months so he's totally fine to get off the breast. What's the best way? And how does it work for my boob? If I'm not feeding or pumping won't my breast fill with milk and feel like they want to explode?
