When do you tell DSC they're having a half sibling?

[Needadoughnut]

It will be one year of joint household by the time baby is born. Baby is very planned and loved. My DD doesn't like the idea of having a sibling in general but she's an only child so understandable. His DC are ok for the most part we all get along. I have a very close relationship with his DD ( so much that there's sometimes competition between her and my DD). His DS might be unhappy as he's the least "on board" about all being one family from time to time but things have settled. Do we tell them together? Separately? We know is has to be about the same time, ideally before I start showing.

If it's not I apologise whole heartedly to the OP who is potentially cowering in the corner wondering WTF juts happened to my post

That gives no indication of how long the op has been in a relationship, how long they’ve known the children etc.

Myself and dp have been living as a blended family since August 2018 but have been together since the end of 2015, our dc met each other November 2016.

You’ve made holier than thou assumptions based on a paragraph.

I'm not who you think I am. I've been with my DP for two years now. What dog? We just got a puppy but have never mentioned her in my posts!

Their mother and I get along. She's been here, I've been to theirs she even thanked me for being so supportive of their DD.

The only reason why we wouldn't wait is my age. I'm already considered very high risk and we didn't want my age to be another factor.

The main reason his DS doesn't like being around that much is because his mum's DP takes him out on his own quite a bit. He seems to be very focused on him.

His DD is the opposite and prefers to be here. I guess you just can't please them all at the same time.

My mistake. There are obviously 2 posters who have lived in the UK for ten years, use the term 'identity as Jewish', used to work for a big tech company and have been with their boyfriend 2 years having only split up with their husband 18 months ago who live in a village with children of the same number and sex. Apologies.

When did I said any of that?

Under your current username on various threads.

You posted in December about the XW and your XH touring your home and you hiding in the kitchen because you're understandably not Xw's favourite person.

How is your bf's son? I hope he's not feeling the need to run away any more.

No, he hasn't done it again. My DP thinks it that day was a misunderstanding on my part, I believe this to be true as I've been invited to her house since then and she's been in a couple of times. I haven't hidden since then and instead go to the door and say hello.

He's never claimed he doesn't like being here because he doesn't like me. It has been hard to get to the bottom of it, but ultimately we think it was because he was bored. We got a games console and the problem is a thing of the past. I think it might be his age too, hard to tell.
