Night feed 11 months old

My son is turning 11 months old and he still wants milk twice at night with 3-4 hours gap in between. When he comes home from infant care, he would have his dinner, shower and play before his bedtime at 8.45pm. What can I do to slowly wean off night feed or its just fine and he will wean of on his own? He will cry for milk or just sometimes start to move here and there showing signs of wanting milk. Tried to pat him back to sleep, but it doesnt work all the time. He will eventually wake up for milk again after an hour or two of falling back to sleep. #firsttimemom #firstbaby
