my daughter did every night until she was 3 months, she would get so MAD too!! pediatrician said it was just cause her nose was still so small... sure enough, she grew out of it
I feel like mine is congested a lot too. But I use a nose frida after she gets her baths and we use little remidies saline spray to help loosen it up. Doesn't seem to bother her though I can just hear the boogers when she breathes lol. A cool mist humidifier works wonders too
