Have our two week old kittens got eye infections?

[CookieRookie]

Morning

Our five kittens have just begun opening their eyes but two of them still have one eye glued shut with discharge. We only noticed this yesterday and we see them everyday so we know this is new.

I was thinking maybe cotton wool and warm water to free them and if it doesn't clear by tomorrow bring them to the vet.

I don't want to over react but I know that their little eyes are very sensitive and they could actually loose their sight if an infection goes untreated.

Should I wait or bring them all to the vet today? Is this normal when they start to open their eyes for the first time?
