What we often see with very young children is that when they use words in the other language...
this is because they do not know the words in the target language. So when they are in school and they have to use a word that has to do with home...
then they will probably do that in the home language. And it’s also the other way around. So, what you often hear is that children...
who come home from school and start talking about school in their home language,
that they will occasionally use Dutch words, that they will occasionally use Dutch words, because they learned all those things in Dutch.
That’what I also see at home with my daughter. And that’s just normal...
Bilinguals sometimes also sound a bit different than monolinguals. I also hear that at home with my own children....
And yes, that is also the case with bilingual adults. I do not sound the same in English anymore as I did fifteen years ago...
when I wasn’t speaking two languages all day long.
