My son is usually happy and chilled, not sensitive at all…until someone coughs, sneezes or blows their nose. He looks at them in horror and starts wailing inconsolably. Cute and funny until one of us has a cold or flu or we spend time with people with hay fever etc. I feel so sorry for him because he’s crying all the time at the mo. I’ve had flu for two weeks and it certainly hasn’t desensitised him. Anyone any advice that might help, or anyone has a baby who does similar and can tell me how long before he grows out of it?
