Pink eye???

Li

My 20 month old son caught hand foot mouth disease about 1 week ago. His blisters are fading and scabbing and he is in a great mood. However, I noticed yellow discharge from both of his eyes today. Every time I clean his eyes, the discharge comes back. His eyes look normal and aren't swollen. Anyone know if this is a side effect from hand foot mouth disease? Pink eye? Something else? I swear, my poor kid can't catch a break. Ugh 😢
