I've had this question now so many times, and I keep getting amused and bemused about it every time. I really don't understand this question at all.
The answer is simple: "Yes, of course I do!" I'm Swedish - I speak Swedish. That's my language.
Unfortunately no, Nathan doesn't speak Swedish so we have to communicate in English; and the kids speak English with most of their friends and at school. But all that doesn't affect my relationship or communication with my kids, we still speak Swedish with eachother.
Someone even wondered if I choose to growl at the kids in Swedish so that other people wouldn't understand that I'm telling them off? Ehm, no - I tell them off in Swedish, because I'm Swedish. It's that easy. (Besides, there is no doubt about when I'm angry with the kids, you can for sure tell that by the tone of my voice anyway.)
You would think that down here people would be more used to bilingual children, but apparently it's still confusing and strange to some. Maybe it's because Swedish is such a small language, they wonder if it's worth it? Maybe the question arises simply because they have no knowledge about Swedish or Sweden, it's not as strange to be English/Malay bilingual.
I don't know. But yes, I speak Swedish with my kids - anything else would be unnatural.
