My baby has had a cold the last week and a half and a chesty cough the last few days, he has a viral rash all over his body which looks horrible and has now spread onto his face/eye. He also has been doing no/really watery poos and generally looking down and vacant. I've been to the doctors and they've told me it's a virus and I know he's ok and there isn't much I can do but it's such a shitty feeling seeing your baby unwell and being unable to do anything about it 
. I guess I just wanted a bit of sympathy or something as it seems to be going on for ever . He is 7 months old btw. How long does this last for?
