Hi, Jo,
It seems like your kitten has an infection affecting her eyes and nose. maybe her mum was a carrier and gave it to her. Your vet will be able to provide you with eye ointrment or eyedrops ehich should help. In the meantime, clean her ayrs and nose (in that order) with cotton wool swabs moistened with warm water to which a little salt (1/2 teaspoonful in a pinthas been added, using a clean swab for each eye an her nose.
