Stuffy nose

Katie

My daughter is 8 weeks old. At 5 weeks, she and my whole family got Covid. She barely had any symptoms and did fine. Like I said she is now 8 weeks old and still has a stuffy nose. We have tried a humidifier, steamy bathroom at bath time, and saline spray and sucking her boogers. No matter what I have tried she still has a stuffy nose. Any suggestions?
