If your 11-month-old son has had a small red bump on his eyelid for over a week with no improvement, it could be related to a chalazion or a stye. You can try applying a warm washcloth to his eye for 10 to 20 minutes during nap times to help the skin heal. If you're unsure about the diagnosis, it's a good idea to consult a pharmacist who can confirm and recommend the right treatment.
