AIBU to say no to being my step sister's birth partner?

I have 2 sisters, a half brother and a step sister.

I was a birth partner for one of my sisters, along with her husband, 10 years ago when she had my nephew and then again when she had my niece 6 years ago.

My step sister is currently pregnant and has asked me to be her birth partner. I have thought about it and I don’t want to. She doesn’t want her partner there and he doesn’t want to be there anyway and she doesn’t feel comfortable asking anyone else. We are not close though and I really can not imagine being in the room when she gives birth.

She is due mid October and I was hoping to go away for half term with my husband and children*, so if I agreed to be her birth partner, that would possibly put an end to those plans.

She hasn’t asked my sister and I’d say we have the same relationship with her, not that I know of my sister would be willing. She has friends. AIBU to say no? I don’t want to hurt her so how do I say no without saying I just don’t feel close enough to her to be her birth partner.

With relation to this little gem

'i can’t really understand why you helped one sister previously but won’t help this one but it’s probably in the thread, I just haven’t gone thru it all.'

For someone that has haunted the thread like a malevolent ghost, surely you know that you can click on 'See all' next to the OP's original post to see the posts where OP has told us how traumatised she felt when she was her sister's birthing partner after her own traumatic births. She hasn't told her step-sister this because she is worried about it getting back to her sister who would then feel guilty.

You are full of sympathy and empathy for OP's step-sister who isn't reading your posts while being callous and massively judgemental to OP who is reading them.

The 'off-hand 'comment about OP paying for her sister's doula was nothing of the sort. It was just another attempt to try and guilt trip OP and make her feel bad.

Agree.

tbh the offering to pay thing was an offhand comment - I have no idea what your or your sister’s financial situation is.

if you can’t be a birth partner, I suppose I would just want to make sure she did have support (helping her find a doula, making sure she had a friend committed etc). if she is very hard up and the father won’t help and you’re better off, perhaps financial help, but no of course that isn’t your responsibility.

i can’t really understand why you helped one sister previously but won’t help this one but it’s probably in the thread, I just haven’t gone thru it all. Ultimately, you can have whatever boundaries you want so up
to you.

overall, sounds like you’ve made your decision so that’s fine. Wish you and your sister well, I hope she has a good birth.

Wonder if all the goady “you need to do it or pay!” Posters will all chip in to pay for the doula… it’s the kiiind thing natch…

They’ve gone very quiet. 🤣

Doesn't necessarily make a difference in some family set ups, but it's quite clearly step sister - not sister.

I sent a message to say that I can’t be her birth partner mentioning that I’d find it far too emotional after my past experiences and that our holiday is around the same time. I wished her all the best for the rest of her pregnancy and birth.

I’ve told my sisters I was asked so it’s possible she may ask them, to give them time to think about whether they could do it or not if she did ask them.

I think you have handled it well being kind but prioritising your own wellbeing.

I can’t believe someone actually suggested you should at least pay £1k for a doula. Mumsnet is nuts sometimes.

If you don't consider her family then fair enough, don't do it. But if you do, well. I can't imagine rejecting a family member at such a vulnerable time in their life.

The majority of these posts astonish me. This is what we've become as a society.

I can't imagine being so dismissive of a woman's birth trauma and another woman's need for support at her birth as to try and guilt the former into doing it despite clearly not being in a good place. On a forum full of women too!

This isn't something that can just be sucked up. There's potential for OP to do more harm than good here, it's not like being asked to fill up a freezer or help DSS deep clean before the birth.

Why does that mean I should ‘at least’ pay for a doula?

I have things that aren’t ideal in my world, should my step sister pay to sort those things out? 🙄

I mean in an ideal world her sister would have a supportive partner who would be there with her but it sounds like that isn’t the case?

Life isn't ideal for many people. I still don't understand why this is OP's responsibility.

Stepsister is an adult and has made her choices. If anyone deserves judgement here it is the father of the baby, OP doesn't have anything to do with it really. They haven't even seen each other since the new year.

Why would OP pay for a doula? Her stepsister is an adult and has made the choice to have a baby with someone who she hardly knows. Why can't he pay for a doula? Why is OP expected to take more responsibility than the actual father of the baby?

Are you equally astonished and appalled that OP's step-sister's fiance, the father of the baby, has refused to be her birthing partner? Isn't he family to OP's step-sister too? Or is his excuse that being present at the birth might 'put him off her' very reasonable and understandable so no guilt should be attached to him?

Indeed.

Expecting a woman to step up when the father is right there. Society needs to shame men more and leave women the hell alone.

But it does sound like mild discomfort (or mild anxiety if you like) vs the scary experience for your stepsister of giving birth with a very limited support system.

You can say no, but I feel really sorry for your stepsister. Could you contribute to a doula to support her instead at least?

Yes. You definitely need to be a medical professional to know that birth can be a very vulnerable and difficult experience 🤔.

I couldn’t leave a family member to do it alone. If the OP doesn’t want to do it, that’s her prerogative. If it were me, I’d rather expend a grand on a doula than let my sister give birth with no support. 🤷‍♀️ Honestly why is that funny?

You seem think that it's OK for you to tell OP that her traumatic experience of childbirth and being a birth partner for her sister was just 'mild discomfort' or 'mild anxiety' when it really isn't OK.

The fact that you sanctimoniously declare that you would pay £1k for a doula really doesn't make you look good. It might be true but it is much more likely that it is a load of guilt-tripping bullshit designed try and to make OP feel guilty.

Also, £1k is a lot of money for many people and if anyone should be paying it, it should be OP's sister's absolute twat of a partner. It's the very least he could do.

You said it sounded like mild discomfort or mild anxiety. It’s not. I have a diagnosis from qualified medical professionals who have treated me.

I won’t be paying for a doula. My step sister is an adult with a job, as is her partner. Their bills are for them to pay.

I’m just waiting for all these kind posters volunteering your time and money to next suggest you either be or pay for a night nurse to help out at night so the father doesn’t have to!

OttersOnAPlane · 30/08/2026 16:27

What on earth did I diagnose the OP with?!

I guess I’m just family oriented. I honestly don’t get why it’s so bizarre to want to help a family member. If I’m weird that’s fine, still wouldn’t leave a sister to give birth alone (unless she wanted that ofc).

Thanks to a suggestion on the thread, I’ve said I’m going to say it will be too emotional for me due to my experiences, and with us probably going away around the due date, I can’t do it but I wish her all the best.

That sounds like a good plan OP.
