19 month old, does anyone know what this is I’m so worried

[DinoNuggetsRUs]

My 19 month old has conjunctivitis, was crying blood tears yesterday so we took him to the hospital. They didn’t seem concerned. He’s also just got over an ear infection. Now, I’ve just seen these in his mouth, does anyone know what this is I’m so worried but I don’t want to put him through another 4 hours in the walk in centre if not needed as he just screamed for 4 hours straight. I’m referring to the white patches inside his cheek. It was hard to get a good picture

Aw bless him, poor little lamb. If he’s been on antibiotics it’s likely to be oral thrush, very common. I’d make an appointment at your GP if anything rather than dragging him down for a long wait

Or maybe the chemist actually. I’m sure you can get something otc if it’s oral thrush, which I suspect it is.
