Same happened to my son! She said how ever long a cold lasts for you to double it for a baby. So she said typically 10-14 days to be over a cold bc as adults we can blow our noses, cough it up, etc. and babies cannot. She always told us as long as it doesn’t sound like it’s in his lungs (wheezing) then just let it be. There’s no real meds for babies like there is for adults so just do your best to suck booger’s out, use a humidifier, use baby Vick’s on their feet/chest.
