my newborn's nose has been perpetually blocked for 2 weeks.

It's been 2 months already and she's still having congestion. We can hear that her nose is congested, and we think she has phlegm built up too. We have tried almost everything we could Google. Saline, aspirator, elevate her head, humidifier, purifier, TCM kitz cough powder, but every morning she wakes up with obviously congestion nose/throat. Went to pd three times and they all say it's normal and common for babies. They just have to outgrow it. It's very sad to see her having these difficulties. She should be a happy smiling baby. I can only hope one day when I and her wake up, the congestion has cleared..
