My daughter has been sneezing for the last few days and brought up nearly all her milk few days ago. But last night she screamed out 5 or 6 times and the night, I comforted her, sometimes it was easy, sometimes it took ages. I tried some saline nasal spray as she was sniffy but didn't work. Then I tried calpol the final time and it worked, but she was still moaning afterwards, What could it be? Just a cold or more?
