Typically we are on holiday atm (still in the UK) when DD (4) woke up this morning I saw her left eye was producing yellow gunk in the corner. I've been wiping it with cooled boiled water on cotton wool every 20 mins. It looks watery & a little bloodshot. It seems to be producing more yellow gunk than before but not really bothering her a lot. Not sure if it's sticky eye but I googled Conjunctivitis & it said it gives the red eye appearance. She's never had this before, is it a GP job or a treat it yourself?
