Sleep woes

Hi, my 5mo son sleeps besides me in bed every night. However after 1-2hours of sleep he will start to fidget and his hands/feet will move. Sometimes I think it is a signal for milk so I feed him. Most times he is just active even though im sure he is trying to sleep. I’m not sure whether he was having a dream or he wants more milk or he is adjusting his sleeping position to breathe better since he has stuffy nose. He sleep sideways and cries sometimes when his nose is blocked. He doesn’t get enough quality sleep and feels tired in the morning. May I know if this happens to you? What would you do?
