My problem is that teh wife does not like me spaeking welsh to the child and if she hears him say anything in Welsh she goes mad. She seems to think it'll confuse him knowing 3 languages and she doesnt want him to be able to have private conversations with me and my mum.
Welshguy, please feel free to use me as an example. My mother CONSTANTLY apologises to me for being so blinkered and narrow minded with my father about Polish "what do you want to teach her that for it's no use to anybody".
Whereas if I could speak Polish I'd be able to set myself up with some very specialist skills to teach here in Poland as well as being a native speaker.
PLEASE speak to your child and keep a language which is unique alive!
Oh yes - a child can learn up to FIVE languages at once, naturally. Linguistic fact.
It makes me sad to see such discord though - I have to ask you, how long did you know her before you got married?
Polish parents ARE over protective. Living here is giving me insight though, my father trying to make sure I was "warm enough" all the time. It's the 1st June and it is FOGGY out there. FOGGY.
Just be assertive, explain why without threats and ultimatums (they are counterproductive if you are not committed to following them with definite action) and tell all concerned exactly why you are doing it. Then stick to your guns. If you do this long enough then all SHOULD be fine. If it is not then there's other issues you have to think about, again without threats.
