F had this a few weeks ago. We were away for the weekend so popped into the local chemist and asked the pharmacist to take a look. Luckily, as F is 2, the pharmacist was able to give us some drops for it and they worked a treat after just a day. We were told that if F had been under 2 years then we'd have had to see a doctor. Can you perhaps get an appoinment tomorrow?
ETA it started out with slightly crust eyes when he woke up for a couple of days. I didn't think anything of it until literally in the space of a couple of hours one eye in particular looked really gunky and the eyelid was red and a bit swollen. He'd also been in a foul mood that week which I think was connected.
Yeah, I could get an appointment tomorrow for her, they have a drop in so will pop by in the morning
