My 7 week old is congested what can i do?

Nasal wash: At 7 weeks the primary cause of congestion is the environment. House dust, fragrance, perfumes, detergent or cleaning products all leave scents that may not bother you but irritate a babies nose. A good nasal clean out with saline can remove much of this irritant load, but removing the offending irritants from babies life helps more in the long run.Air particle filters can also help.

Mgt and follow up: I would advise gently using infant saline nasal drops and keeping the passages clear. If there is any fever, cough or other symptoms, please let your pediatrician know. Babies at this age breathe through their noses, and keeping the passages clear is important. Sometimes there can be an anatomic narrowing which will be assessed at the doctor's office.
