Cereal in breast milk?

Im really wanting my son to sleep through the night. Ive been falling asleep during his night time feeding and its really worrying me. Can i put cereal in his last bottle for the night to see if he'll sleep longer? If so how long can a cereal bottle stay at room temp because i usually have a bottle ready when i go to bed for his middle of the night feeding can i still do that?
EDIT: My baby is 4 months old and this is when i started giving my oldest cereal too but he was on formula by now so i didnt know if breast milk was different.
