Stil breastfeeding

My son is 1 yr and 8 months and is stil breastfeeding through out the day and even at night sometimes he’ll wake up a couple times a wanting to nurse. I want to start weening him but I have no idea how. I’ve looked it up and know that I should slowly remove nursing sessions one by one and offer food instead but my son is super attached to breast milk and I’m having a hard time. Can you guys give me some tips
