We found out last week that 6 year old DS is colourblind. The optician said it was nothing to worry about. There are a few things that make sense to us though. DS amhas always struggled doing puzzles (I think he struggles with the colours) and he takes ages to find Lego pieces when doing a set (I think he can't use colours to find them).
I'm not overly concerned but was wondering if you have a colour blind child are there any activities where you notice it? I'm feeling dreadful as I previously told DS to 'match the colours' when doing a puzzle which he genuinely couldn't do!
