Today is the first day I've ever used the NoseFrida (and actually got anything out!) But after a particularly tough suction-session, I almost instantly felt something wrong in my throat. Ugh. I feel like something is coming on. Is the filter supposed to prevent germs from going into my mouth, or is just to prevent actual snot? Did I just inhale all of LOs germs (her first cold). I haven't been sick since she was born.
