Where is the best place to go? DH and I are both doctors although not paediatricians, so while we've used online info to pretty much diagnose DD ourselves, we don't know what age she should go to an optician to get our suspicions confirmed? Any experience? (She can't distinguish red or green from each other or from black, and describes lots of colours as purple if anyone is wondering why we're so sure!) any advice appreciated with thanks 😀
