Dyslexia in kids..

Hi guys, my son is 7 and in year 2.. he is really struggling at school, especially in English. He finds his phonics really hard, cant write to the stage most kids can in his class, he reads words backwards, like hell sound out t a p and say pat.. or hell just read a completely different word...

Can someone help me..

I done a dyslexia test thing online, some website called lexcersise and it came back saying this.. has anyone done thing..

Has anyone got a child who's dyslexia..

Can you tell me age you first started noticing..

What were the first signs..

And what do I do from here..
