We are a couple living in Sweden, my partner, F32, born in Germany (mother tongue German), and me, M49, born in Sweden (mother tongue Swedish),
We are expecting our first child in August, and feel that OPOL seems like the natural choice for us, wanting to give our child the gift of two mother tongues.
My partner has been living in Sweden for approx five years, and during that time adapted Swedish well. She speaks fluently, only with the occasional small grammatical errors, ans still learning the more unusual parts of the vocabulary.
In the beginning of our relationship, about four years ago, English was our common language, but this has gradually shifted to the point we are now, where we almost exclusively talk Swedish with each other.
When discussing multilingual upbringing with another friend, with multilingual experiences himself both as a child and parent, our friend strongly suggested that we should bring back English as our language between us when applying OPOL in our child's upbringing. The reasoning behind that approach was that if we continued in Swedish (which also naturally is the community language and the language of other relatives here) we would face a risk of the German getting too weak a position with the child. In other words, when the child hears and understands that Swedish is the predominant language within the family, the child would start to speak and answer in Swedish, both with my partner and me, even though being addressed in German by my partner.
Also, reasoning further, it would help the child to get in some touch with English at an early stage, thus introducing the benefit of a third language. English have a strong position in Sweden, so it would be studied from first grade anyway, but the idea would be to give the child a head start.
On the surface, this logic seems reasonable, however when searching online (including this thread) for this particular aspect we didn't initially found much.
Could anyone here maybe help provide some answers Is this an issue being discussed at all? Does it exists scientifically sound evidence, for or against?
Thankful for any input and/or experiences!
PS. Maybe I should add in, for context, that I myself is NOT fluent in German at all. I undesrtand a bit, as an advanced bginner perhaps, but still have quite difficult to talk on a conversational level. I though have the ambition to learn the language much better, in order to connect and interact with our child's German relatives and for other good reasons as well.
But I feel it would be a disservice to the child, or the language enviroment at our home, if I tried to speak my (bad ) German too much around the house during the upbringing.
