How to wean quickly!

Bri

My son is 15 months old. He eats almost anything throughout the day but he still wants my breast (about 5-6 times a day). Most of the time he asks for it when he’s tired or just needs comfort

Anyway, I just found out I’m pregnant and want to wean my son. I’m stressed about the fact of being pregnant and nursing and would really like to stop

I need advice and tips to wean my son as quickly as possible?
