Nothing. Ears are self cleaning so it isn’t necessary x
If I can see it’s mostly out I’ll fish anything visible with a cotton bud, but only because she sits perfectly still and lets me. And only really had to do that twice so far. Otherwise I leave them be.
Drop of olive oil in the ear before the bedtime. That’s what our audiologist doctor recommended us and it’s working pretty well
My daughter has loads too haha I just use a cotton bud to clean them. Just don’t put it into the ear, just clean what wax you can see.
