Night weaning

How is this done??

My baby is 10 months, my goal was 6 months and now I just want to be done by 12. I’m exhausted.

A little background - he refuses to nurse unless it’s to sleep, but lately well the last week ish, He’s nursed before bed and then gone down on his own. During the day he straight up refuses the boob unless it’s just before his morning nap.

He started refusing any and all forms of formula and pumped milk around 7 months so this was the arrangement we made. Since he wasn’t nursing during the day I let him get up twice at night to nurse. He will randomly sleep all through the night which is great but it’s random. He also goes down on his own for his afternoon nap - with occasional fussing and sometimes we have to go in and settle him. I would love to get down to just once a night and not at all by the time he’s 1 but I have no idea how to go about this. He’s also been teething so his twice a night is sometimes 3-4 times, though I refuse to nurse him on the extra times and he usually goes back to sleep if I go in to him.
