Try to be super clean and wipe stuff with Milton. Encourage him to keep hands off eyes.
Keep his eyes and his hands as clean as possible. And good idea to change pillows (if he uses one_) or sheets. Mine had this so much when younger but when it got very bad I turned into a clean freak and it got better by itself. (not implying your diryty in any way! I know once it had cleared we'd go to playgroup and it would go gunky again!
I bought little saline solution sterile water things from Boots. Mildly salty water for when we were on the go and couldn't get boiled water. HTH!!
Thanks Taking him to the nurse prac this moning as his eyes were glued together this morning, hopefully they will prescribe something. Will chenge bedding etc when I get back and keep squirting milk at him!
