Today, I noticed my baby's ear was almost blocked by earwax, a sticky, orange-red substance. I removed what was visible, but later, a liquid that looked like it had blood in it and smelled bad started coming from his ear. Concerned, I went to the pharmacy and got some eardrops, but the liquid is still coming out, though in smaller amounts. My baby, who is 18 months old, is active and doesn’t seem very bothered, except for occasionally rubbing his ear or putting his finger in it. I'm unsure whether I should wait until tomorrow morning to see a doctor or seek immediate medical attention.
