It's a difficult question you've got there,
@enea2016 , and I hope you find the answer to it.
If I was in the same position, I'd probably think, well, what are me and the wife going to say to each other in twenty or thirty years time when we talk about our decision all those years ago to not have a kid just because I happened to be T1?
I reckon we'd both deeply regret not having a kid just because there was a statistical chance that he/she
might become T1.
Statistics and % chances of your offspring being T1 are one thing. Living your life is another. No-one gets anywhere without taking a few risks.
You're recently dx'd. Please don't make any life changing decisions about whether or not to have kids so early on in your T1 life.
Your perspective on it might change once you've lived with it longer. It's quite common in the first year or two after dx to see it as this overwhelmingly negative thing where the idea of having kids seems impossible, but after you get used to it, you might start thinking, yeah, I can manage this.
Best wishes, man.
