Little kitties whose eyes are not completely open have a condition called neonatal conjunctivitis. This occurs when the skin of the eyelids does not completely separate. The glandular secretions from the mucous membrane below cannot escape from the eye, so it builds up. If you can take a wet cotton ball and gently tease the eyelids open, they usually separate quite easily. These are not infected.
As for the mother, if her eyes are not red and goopy, but just have brown matter, whe may have a blockage of her lacrimal duct that drains tears fom the eye to the nose. Have the vet check the cat as soon as you can get her back.
