My baby is still SO congested, I've religiously been applying baby rub, giving him vapor baths, suctioning his nose, using saline spray, even took him to the ER and they used a "high power" suction to get it out. He can barely nurse because he can't breathe, he is so miserable I don't know what to do! But I've done everything correctly from what every doctor has said. 😕
