My 6.5 month old has a cold. Poor little guy is so congested. We have tried Zarbee's baby rub, steam shower, saline, nose Frida, humidifier, essential oils...he is not better. Today he is having a hard time nursing. Am I missing anything? Obviously if he continues to struggle eating I will take him to doctor today. He was just there last week because this all started as a watery eye that got infected. Then a couple days later, bam.
