Hi there!
as a tunisian french mum bilingual myself I would be glad to hear about your experience.
Does your kids speaks tunisian? mine does well she's only 21 months but still she does her dad isn't tunisian but I have the advantage of being the mother and I really understand why we call it mother tongue
Well I know that most of couple here the man is tunisian (no Kris and Hajer I am not forget you how could I) so I was curious to know if they teach tunisian to their kids?
Once again sorry for the writting is not good I am not a native speaker!
Have a nice day
