I think u can continue to try to encourage him. Maybe for the first few times u can satisfy his hunger w a small feed from the bottle followed by latching. If u co sleep or baby is sleeping v near u, giving him to boobs during his drowsy night feed is a good option too. Just continue to encourage, don't expect too much for 1-2 wks. Some babies also go through sleep regression or teething or just fussy at night - these are times when they will take the breast quite willingly
