I think I quoted here on auxlang a 
report that Danish children were 
supposed to need mor time than 
Swedish children to master their 
mother tongues. The explanation 
given was that Danish children had 
to cope with more reductionin 
pronunciation so that the language 
was supposed to be more blurred and 
thus more difficult to master.

I once had a student in one of my 
Swedish groups who was from a North 
African country. He maintained that 
you cannot do maths in Arabic. I 
guess he had attended school in 
French, so the Arabic he was to 
learn was classical written Arabic 
as oppposed to his dayli colloquial 

In the Arabic case you can speak of 
some sort of "diglossia" where the 
colloguial and classical language 
in fact are two different languages 
as if you would write in Latin and 
speak French or Italian. (I don't 
know if the difference is that big 
in Arabic, but as classical Arabic 
is what people are supposed to 
write, i imagine that the written 
Arabic is closer to people than 
Latin is to the French and Italian).

And you have the problem with 
dialects vs the national language 
and the relative severeness of a 
written standard. As I understand 
it Polish is less tolerant to 
colloqualisms and dialects than 
Swedish and very much than 
Norwegian. But if children learn 
those languges faster, even as 
compared to the standard, is 
nothing I dare have an opinion about.
