Maybe discuss with your doctor, it's not something I've heard of before. DD had a shocking cold when she was 4 weeks old and could hardly breathe... we found this thing called NoseFriida - basically you put it in bub's nostril and suck the snot into a tube. It sounds and is completely revolting but when you are desperate and your baby can't breathe it is amazing the yuck factor you can get over! Hope it's nothing and she's breathing clearly soon xx
