Is it normal for my aunt and uncle to hide this secret from my cousin?

It's horrible but it's normal that fetuses and infants die. A child that was had after that isn't considered a replacement, just another kid. He could have but he never did have any siblings. He should be told about it some day, but that is for the mother to decide in my opinion.

Don't tell that's none of your business to do so. Trust me. You could do a lit of harm. The child does Not need to know this they might not understand.

Why would you feel it is important to say something devasting to another human being like "they are a replacement"? What are you trying to accomplish? Ruininh their self esteem just because you are a busy body? Grow up. Sometimes you need to mind your own business rather than get involved in something that has no purpose other than devastation. Maybe at the time the child was a replacement for all the loss suffered but not a literal replacement of another child. Tgat can never be replaced. Saying something like that can only rob your cousin of self worth and ruin tgem emotionally when you can't possibly understand what you are talking about. Another sad example of someone feeling the need to create drama and ruin someone elses life because you arent happy with your own.

I wouldn't feel traumatised if I was told. I would feel glad that my parents cared enough to try and have another kid or I wouldn't have even been born. For the same reason, I wouldn't feel offended if I wasn't told until I was in my 30s, or even if I was never told at all.

However, I am also a very strange person. I am sure that most people would care, in the same way that most people would care if they were adopted or not, when I wouldn't care at all.

Don't tell him though. Ffs, the kids only 10. Wait 5 years, then he'll be mature enough to know how to take it in context, if his parents haven't told him already.

He should be told. Why shouldn't he?

It's not like it's going to impact him or turn into some kind of soap opera.

That to me would've traumatizing. It's really none of your business.

it depends on the maturity of your cousin. Some 10 y.o. may be able to handle and comprehend. but it's definitely not your place to tell him. me personally, if I were 10 I don't see why I would need to know that information at that age.

Don't be an interfering fucknuckle. It is none if your business

its non of your business if the parents wish to tell him then they will if not then its not for you to tell him.

no offence its between the parents and the child.

It isnt like theyeve killed someone its just like that theyeve had childrens before whwen i was kinda 10 too i founded out that my father had another child that died and i wasnt mad on him. so he should know its the best , because its not souch a big deal

They will tell him when they think the time is right. It wouldn't be so great if he heard it from someone that wasn't his parents.

Hopefully u dont tell him.. N ya his too young
