How to wean off milk at night

How do you wean off your infant from milk at night? My 7 mth old going 8 mth (born premature, corrected age 6 mths +), still wakes up twice at night for milk. He eats solid twice a day and normally will drink milk before he goes to sleep at 7pm+. Then wakes up at 11pm-12am for milk and another one at around 3am before waking up in 3-4 hrs time and never go back to sleep until he baths. He's also on a pacifier. I'm a SAHM and very tired during the day as he is also very clingy and I would love to have an uninterrupted sleep at night. My husband also helps with the night feeds. His screams for milk wakes us up rudely. I cannot 🥴
