benadryl is not a nasal decongestant and will do nothing for the stuffy nose (not to mention this medication should not be given to a child this young. ) you want to use saline drops to help thin out the mucus in the nose and then use a nasal aspirator to help clear the passageway. i also recommend running a vaporizer in the baby's bedroom -- that usually helps a lot as well for congestion. parents need to be very careful about cough and cold medications in infants and children so take the time to talk to your pharmacist.
is there a safe dosage of benadryl i can give my 5-month-old baby who is battling a very congested nose?
