My 1-year-old baby regularly pulls his ears and scratches the insides until they bleed. I often clean them and dry them well after his bath.

It is difficult to determine the exact cause without more information, but it is possible that the accumulation of earwax may be the issue. You can try applying a few drops of mineral oil in the ear to soften the wax and keep the ear hydrated. If the situation does not improve or if your child develops pain or a fever, it would be best to consult a doctor. Hope this helps, and have a great day!
