And as an adult, you don't subconsciously sound out all words u read. That's a myth. U simply register their meaning.
Perhaps your son would have had reading difficulties in other languages too, but it's unlikely.
When the spelling code is not constantly obscured, when identical graphemes always make the same sound, i.e. if 'ou' can be relied on to sound as in 'shout, out, loud', learning the code is easy.
It's the 2039 common words which don't obey the basic English spelling code which confuse many children (e.g. group, double) and ensure that all English-speaking children take far longer to learn to read and write than in languages with better spelling systems.
I apologise for pasting the graphemes with irregular spellings again, but imagine learning to read with them having just one pronunciation only (as in the first word). That's the difference between English spelling and more regular writing systems.
