Newborn is 2 weeks old today and has had some congestion so decided to use the shnuffle babe nose aspirator in one of her nostrils. As soon as I used it on her she started acting a bit strange, she now looks uncomfortable and is making weird snorting/mucus noises in her sleep! I'm so worried I have done something serious to her or caused damage, I feel awful! What could it be? :( :(
