My child is 19 months and he's been really healthy for about a year....He was in the hospital off and on for the first 3 months... So it's still kinda foreign to me at what point they need to be seen... He's coughing a lot and I've given him albuterol but that didn't seem to do much for him.... He's got a runny nose... But his coughing is what has me the most worried. It's only been going on today... At what point do I bring him to the hospital?
