My 5yo son regularly writes words and sounds jumbled, for example he wrote “uoy” for “you” and “on” for “no”. He also writes the sound “ai” as “ia” and other similar things.
When reading he’ll often replace / guess a word ie he said “river” instead of “water” the other day. When I ask him to sound it out he will then get it right.
I’m thinking these are signs of dyslexia as I noticed the sound reversal in his sister at this age who is dyslexic.
He’s just turned 5 (about to go into year 1) so he is young in his year but is this common at his age or shall I be assuming he is dyslexic too?
