Baby's and congestion?

My son is 5 weeks old and he's sounded congested, at night, since we brought him home. For the past 2 nights, he's sounded really rattly up in his sinuses. Yet..He really doesn't have a runny nose. I use Little Noses and use the sucker to get some boogers out.

Do you think a steam humidifier next to his bassinet would help? And for how long?

A cool mist humidifier.

Are you BF'ing? You can put some of that into his nose and use the bulb aspirator.
