My 12 month old caught a cold from her cousin. She has a really bad runny nose and cannot breathe through her nose. Thankfully she has been breathing through her mouth but is there anything I can do for her?

We cosleep so last night I was up all night spraying saline into her nose while she slept (she will not let me do this). When it was really bad and she wouldnt stop crying DH helped me hold her down and nose frida-ed her nose.

I did put some baby vicks on the back of her shirt but it didnt do anything. She has so much mucus from last night she had diarrhea (sorry if thats TMI) this morning.

Please any advice would be appreciated.
