And I feel far better about it than I thought would :)
I have been struggling with still bfing him for a while now, given the chance he would feed all the time. I've had several unsuccessful attempts to just go cold turkey that left me feeling very full and uncomfortable, but since last week he hasn't had a single feed and I've not even felt swollen, so I assume for the last few weeks he's not really been getting much at all. Following all the advice on here I managed to cut out his mornng feed quite easily by getting straight up and serving breakfast rather than snuggling up and letting him latch on. Bedtimes have been the real struggle, but last week I let him pick his own sports cap type bottle (peppa pig if you want to know!) filling it up with milk at bedtime, reading him his story and then syaing goodnight. Basically getting a bit stricter and more routine-y. There have been no tears and no questions. The first night he did ask for his milk, but I told him it was broken and I had to go to the doctors to get it fixed 
. It's the only excuse he's understood, and he seems happy with the explination.
It does seem a bit sad to think he'll never have a breastfeed again, I didn't do anything to make the last feed special as tbh I didn't know that it would be the last feed, but it feels such a relief that it's finally gone so smoothly :)
