Isla has it, and given it to me, she was also hospitalised for a few nights last week, tube fed and had two hourly drainage.
All you can do is make lo comfortable and feed little and often, do your best to clear the airways as babies have to breathe through their noses when feeding (isla was suffocating when she fed so refused) cot elevated, plenty of cuddles etc.
She is soooooooooo much better now, not over it just yet but they spring back very quickly. The hospital did not perscribe anti-biotics as they will not work on the virus but are useful if lo develops a secondary baterial infection on the chest. its really bad this year, they had to open another ward whilst we were in as there were so many admissions.
Trust your instincts tho, and take lo along to hospital/docs if you feel the need.
The docs told us that day 6 was the worse, as it follows a pattern and after that they start to imporve.
Hang in there hon x
