I am currenly seething as 14 month DS has horrible bacterial conjunctivitis in both eyes. When I was collecting DS from nursery last week I over heard a conversation between staff and a mother advising her not to bring her daughter in the following day. It turned out the daughter had conjunctivitis and was on antibiotic eyedrops. The mother was extremely annoyed that the nursery wouldn't take her daughter when she had the infection. I know it's a nightmare sorting alternative care when you're working but I think she's totally selfish. Am I being unreasonable to make a complaint?
