6m old has pink eye is ofc very itchy what can I give him so he can sleep 😩

——update, he’s been diagnosed for a week now he had orithimycin ointment (probably not spelled right 🥴) but the cream is just not helping if anything his eye has gotten worse since being seen, but today he had another appointment an has been switched tobramycin drops they’re really good I had them the week before last for my pink eye so fingers crossed this works my little guy is so uncomfortable.
