My 4 yr old had some vision tests at school and I just had a call from the eye hospital who told me that his right eye isn't working as well as it should. He has to have drops at the hospital to look at his eye and I'm so blooming worried...my thoughts are instantly that it's something bad and I'm in bits. Please can someone reassure me that this is routine as the nurse wasn't very reassuring at all and she asked questions like 'is he in good health' well, he's had a cold almost non stop since he started school in September so my brain is working overtime.
