If you are talking about white patch on skin or eye then please discuss with your doctor dear anon.

Hi Anon is it like the whitish material in the corner of the eye or on the lid? If inside like mucous, then nothing to worry it might be a blocked tear duct. Tears run down the baby's cheeks and might accumulate in the corners of the eye overnight while he sleeps. He might wake up with a collection of whitish material in the corner of the eye. But if it's like a patch on the eye lid pls seek your docs advice asap. Pls meet the doc for proper guidance
