Is it irresponsible to tell your DC you're pregnant in the first few weeks

[pizzaparty5]

Just that really.
I've noticed some people tell their children they're expecting another baby from quite early on, before 12 weeks.
I can't help thinking it's a little unfair, incase the pregnancy is not viable or ends in the first trimester.
Wondering what people's thoughts are?
I have recently become pregnant and I'm not planning to tell my DC until the first scan at the earliest.
Or, perhaps it's best to involve DC in this from the first few weeks? Maybe it depends on their age.

For me HG started before I'd got to the point of testing, so before 4 weeks and lasted till I was in labour. Everyone I knew found out when the vomiting started.

We've just told DS (he's 4) at 14 weeks. Frankly, I'd have preferred to wait but we told people after the 12 week scan as it was getting difficult to hide - I'm already quite visibly pregnant this time. I also wanted him to hear it from us rather than guess from comments made over his head.

We've explained that Mummy is trying to grow a baby in her tummy, and he has seen my DSis pregnant (she's much further on) so he does at least get the concept. But we have gone to some lengths to arrange childcare for my appointments rather than take him with us/me.

It was moot for me as DD was only 5 months' old when I was pregnant again.

If I got pregnant now (notwithstanding the fact I wouldn't keep it, so it would again be moot), I'd only tell them if I thought it was absolutely necessary before the first scan.

I told quite a lot of people including DD(2.5) early on as I was really sick. I didn't want to not tell her when others knew. I figured that she was young enough that if I had miscarried, I would have explained it simply and she would have quickly forgotten.

We told our DS at 8 weeks which sadly ended in a MMC so decided we would wait until 16 weeks as then we could tell him he is having a brother and not "just" a baby but sadly his brother died after being born at 28 weeks.

I think if we were ever lucky to try again and get pregnant, I wouldn't tell DS until we arrive home with his brother or sister

Eldest 2 were close enough together that it wasn’t an issue.
Third baby came along when they were 6 and 7. Waited until I was 4 months.
I had had 3 miscarriages by then and it was painful enough without having them being heartbroken too.
Sickness was explained by me having a bug and needing lots of rest and being looked after. No big deal.
Up to the individual and circumstances.

Each to their own but it just means if DM was to lose her baby DC would also need to be told. Are they at an age they would understand and would the dm be emotionally able to speak about it. It's a tricky one

My partner blurted it out to our four year old at 5 weeks. I MC at 8 weeks and couldn't tell him so had my partner explain it. I'm currently 7 weeks now and I won't be saying until 12 weeks at least.

Depends on the age of child.
I think I was around 10weeks when I told my 5yo he told the GPs. Baby was a long awaited fertility baby I think we would have been devastated if anything had gone wrong.
