10 month old cold sore

[Anyadvicewelcom]

My 10 month old has a very small cold sore on his lip. Otherwise seems ok in himself . I went to the Gp bu they just said monitor . I’m worried it’s gonna get worse or go to his eye and get really bad …

Could you put some of those cold sore patches over it so that even if he touches it he can't transfer to his eye? They don't have to be specifically for cold sores, any hydrocolloid patch would do i think.
