When an infant has a cold there's not too much you can do to get rid of the cold but let it runs it's course.
Even when adults have a cold all you can do is manage the symptoms and help them with the cold but there's nothing you can do to make a babies cold or anyone's cold go away any faster.
But you can help the baby or infant with the cold feel better by using a humidifier in the babies room, using saline drops in the babies nose, giving the baby plenty of liquids to drink to make sure they are hydrated and also suck the babies nose out so that their nasal passages stay clear.
You can use a nasal bulb syringe to clean the babies nose out.
A baby should get over the cold within a week or 10 days just like kids and adults who have colds it will go away within a few weeks at most.
If the cold doesn't go away within a few weeks or the cold seems to get worse take the baby to the doctor or urgent care to be safe.
Although a stuffy nose can make a baby have some trouble breathing a stuffy nose cannot suffocate a baby.
Even though the babies nose may be stuffy they are still able to breathe some through their nose and also they can breathe through their mouth as well.
As long as the baby can breathe through it's mouth the baby will not suffocate from a stuffy nose.
However it's a good idea to also clean the babies nose out to help them breathe better and also use a humidifier in the babies room to add moisture to the babies nostrils.
Just like an adult, kid etc that has a stuffy nose the stuffy nose or congestion will not suffocate you, the baby or the kid.
No you cannot suffocate from congestion.
When you're congested and you cannot breathe through your nose it can feel like you may be about to suffocate but even though your nasal passages are somewhat blocked they are not fully blocked and you still get some air and oxygen through your nose.
So you still are usually able to breathe at least some through your nose even though you have nasal congestion.
Also you can breathe through your mouth as well when you're congested so as long as you're able to breathe through your mouth when you're congested you will not suffocate.
To be able to suffocate you would have to have both your nose and your mouth completely blocked for at least a minute or longer and then when you cannot get air into your lungs you cannot breathe and then you suffocate.
