Maybe I'm not telling you ladies anything that you didn't already know, but the Nosefrida is AWESOME! : )
DD absolutely HATES it, but it does a much better job than the bulb aspirator at getting out the snots. The concept is kind of weird (you literally suck the snot out of their nose), but it works like a charm. However, I am extremely dubious that that little filter would do anything to stop a cold virus from going through. So, I guess in that sense, you use it at your own risk... most likely you will pick up the cold from your kid anyway, right?
