My lb has been congested now for over a week. I had him at the doctors last week and they said it was a cold and his chest is clear which I suspected as my daughter has one. However it doesn't seem to be going away and I have noticed he is a lot worse at night when he is lying on his back. During the day it isn't as bad and he usually sleeps either on me so more upright or in his bouncer. Sometimes it sounds like his milk his coming back up although he swallows it down again rather than being sick. I am now wondering could he have reflux that doesn't cause him any pain but is causing the congestion? Anyone else had this? He is eating fine and doesn't have a temperature. He is waking up loads in the night though and because he can't breathe properly. I am using saline drops to help but they only last a short while.
