Sick baby

My little man recently caught what I’m assuming is a cold. He’s got a runny nose/congestion and a slight cough but no fever. However the problem is these past few nights he won’t sleep in his crib, the only way he will sleep is next to me and quite frankly I’m tired of sharing a bed with my husband and my son (I get like 1/8 of our queen bed 😒) looking to see if anyone has any advice on how to get him back to sleeping in his crib alone?

We have a humidifier going, he’s got Baby Vick’s on his back, chest & neck, and I suction out his nose with the bulb thing but nothing seems to be helping😭
