Is it normal for a very rubbishy chest full of phlegm to make baby keep being sick?? 111 have advised it's normal and may take time to shift, she's had the congestion for over a month, took antibiotics for 2 wks finished 3 days ago and it's got worse last few days with her now throwing up at night. The mattress is propped up and got hot bowl water with vapo in there. Has anyone else had this issue and what happened?
