Cian has had a cold (cough, snotty nose, etc) for the last week or two but just in the last few days he's been having this green gunk - honestly it looks just like snot - coming out of his eyes. At first I thought it was just "sleep", but when you clean it away more just comes out within the next hour... he really hates it when i try and clean it, to the point where he absolutely screams and goes blue in the face!!

so I can only assume it hurts - i've just been cleaning it out with a damp cotton bud.
has anyone come across this before? know what's causing it? I don't really want to go to the doctor and expose him to more bugs in the waiting room if we don't have to but it's not going away so i'm worried it's serious. he's also had diarrhoea for about 5 days that's just cleared up (in case that's related!)
