I need some help ladies. DD is 6 week 4 day and for the past two days I thought she was getting a cold but I'm pretty sure it isn't now. She sounds nasally and when breathing she will snort Someimes. Mainly when laying flat and waking up from sleeping. No fever, she still seems happy, eating well and diapers are good but her breathing is weird. Mucuousy sounding. I've tried a humidifier and saline nasal drops. Anyone else experience this or can put my mind at ease?
