My husband and I have been together for 11 years and married for 9. He is 49 and I’m 38.
He has two older children from his previous marriage, both of whom are still very much part of our household. They split their time between us and their mum, although realistically they’re here a lot. So although this will technically be my husband and my fourth child together, we already have a very full house. We’ve recently announced that we’re expecting our fourth baby together.

I’m obviously over the moon. This baby was planned, wanted and very much conceived because we both genuinely wanted another child. This is our last DH has since had a vasectomy.My sister, however, has taken the news really badly.She’s 44 and with a lovely partner who does have children. She was married for quite a long time to her ex, and apparently he had always told her that he “might” want children eventually. She waited because she loved him and trusted that he would change his mind.He never did.
They eventually separated and divorced and she’s now in the position of being childless when having children is something she desperately wants.

She has said to me that every single one of my pregnancies has felt like a punch in the stomach because I already have three children and am now having a fourth.
I completely understand that she’s hurting, and I have tried to be sensitive. I don't constantly talk about the pregnancy around her I’ve even avoided discussing names etc.
But she has now basically said that she feels I’m being incredibly insensitive by having another baby when I know how desperately she wants one.

This is where I’m struggling.I feel awful for her. I genuinely do. I can’t imagine wanting a child for years and not having one.
But at the same time, what exactly am I
supposed to do? My sister's situation isn't something I can fix. I can't give her my baby, and I don't think it's reasonable for me to not have my baby because she hasn't been able to have one.And, if I'm being completely honest, there is a part of me that feels angry because she chose to stay with a man for years who she knew was ambivalent about having children. She says he manipulated her and strung her along, whereas I think at some point she also had to make a choice about whether to stay.

I haven’t said that last part to her because I know it would be incredibly hurtful.
My husband thinks I’m being far too considerate already and says that while we should obviously be kind to her, our family planning is nobody else’s business.
My mum, however, has told me I need to “put myself in my sister’s shoes” and perhaps accept that she might not want much contact with me during the pregnancy or after the baby is born. I am fine with no contact my life shouldn’t stop for her to be happy.

I’m finding that difficult because we’ve always been very close, and I don't want my sister to resent my baby before he/she is even born.

I’m not asking whether I should have had the baby that ship has obviously sailed. I’m asking whether I’m being unreasonable in expecting my sister to accept that I’m allowed to be happy about my pregnancy despite knowing how painful it is for her.

Both things can be true at once. You are allowed to be happy and she’s allowed to be sad.
You should be mindful of her situation and follow her lead on how much she sees you and how much you talk about the pregnancy.
What she said is unfair and hurtful to you and she shouldn’t have said it. She’s lashing out because she wants you to hurt like she is.

YANBU to have as many babies as you please.

Your sister is unable to help feeling hurt by your pregnancies.

How these two things can be overcome is by talking it out. Tell her you understand, and you're sorry.

She needs to step back a bit while you are pregnant and lick her wounds quietly.

I've been on both sides of this (i struggled to get preg after a loss and had sister in laws popping out babies) and it's not easy for either of you.

Softcream · 21/08/2026 14:17

YANBU to be having your baby and to be delighted about it. But your sister is also NBU if she wants to take a step back and not contact you for a while if that's what she needs to do.

EmailsaysOOO · 21/08/2026 14:19

You can't change how she feels. I think it would be very unusual if it didn't cause a bit of distance to develop. I'd just let her be.

Sahara123 · 21/08/2026 14:21

Difficult. I’ve experienced first hand two family members who desperately wanted children, but for whatever reason it didn’t happen. It became all consuming, all they could think about. I think all you can do is accept that you’re probably not going to have much contact with your sister while you’re pregnant, and then see how the future goes when the baby is born.
Being childless when you desperately want them is pretty devastating.

Smartiepants79 · 21/08/2026 14:24

I think you’re reasonable to be happy about a new baby that you’ve chosen to have. I understand that her behaviour is hurtful and you do sound like you’re trying to be considerate.
But it also unreasonable to expect her to just accept this situation and be as close to you as always. This is deeply painful for her and she is angry that you have so much that she doesn’t. she will also be feeling very guilty for feeling this way, deep down she knows she’s being unreasonable and that you can’t fix this for her.

Vulturesoverhead · 21/08/2026 14:27

Oh just give her the baby, easier all round.

TheFunnyPoet · 21/08/2026 14:32

I’m just not sure what else I can do. Surely she should be happy to have nieces and nephews.

I don’t think people who conceive easily, and as many as they want, can ever really understand how unfair it feels when you can’t. Cut her some slack OP.

I am trying to but she’s said some very hurtful things to me and about my marriage. Her first reaction was pretty much to say that we fuck like rabbits.

Why should she be? What's your reasoning here?

You're not sure what else you can do? Honestly you just need to accept her feelings and understand that she may need to take a step back from close contact for a while.

Well she shouldn’t have said that but it came from a place of great pain, surely you can see that?

TheFunnyPoet · 21/08/2026 14:38

I’ve accepted her feelings but just her saying that it feels like a punch because we are expecting another child. That’s not a very nice thing to say to someone those thoughts should be kept to yourself or asking about our sex life

Exactly this. Have a bit of sympathy for her but equally you don't have to feel bad you've chosen to have another one. And all the luck to your DH coping with a child in his 50s...

Kokonimater · 21/08/2026 14:40

Weird one. Would you consider being a surrogate for her?
ok everyone. Now kill me.

Sartre · 21/08/2026 14:43

She is child free by choice though. She didn’t have to stay with the guy who kept fobbing her off whenever she brought up TTC yet she did and she wasted her peak fertility as a result. It isn’t like she’s been TTC for 20 years and can’t have them. Even if that was the case, does she seriously think you shouldn’t have children in solidarity?

GreyCarpet · 21/08/2026 14:43

As others have said.

You are not at all unreasonable to have as many children as you and your husband want.

Your sister isn't being unreasonable in finding it hard given her own situation.

She has no choice but to accept you're having a fourth child as you're pregnant.

You would be unreasonable to expect her to be overjoyed about it (which you don't).

I’m not asking whether I should have had the baby that ship has obviously sailed. I’m asking whether I’m being unreasonable in expecting my sister to accept that I’m allowed to be happy about my pregnancy despite knowing how painful it is for her.

Its a meaningless question really. You are happy. Whether she is happy about it or not is a different matter but it's immaterial whether she accepts you're allowed to be happy.

Surely she should be happy to have nieces and nephews.

Why? Seriously, why? They're not a consolation prize for not having her own.

I want to be supportive to my sister but also I don’t think I should stop myself from having an another child just because she doesn’t have children.

Wel, obviously. I'm not sure why this is something that needs addressing either. The only people whose opinions on this matter are relevant are yours and your husbands.

You can be sensitive about it but no one would honestly expect you to not have another child because she can't have any. That literally makes no sense.

I think you'd both benefit from having some space from each other. Her because she is obviously hurting from this and you because you seem to be shouting into the void that your decision to have a fourth baby shouldn't be influenced by your sister's sitation and I cant see where anyone has said it should.

Right, I think you’re not being unreasonable to have another baby and of course your sister is being silly to expect you not to have another one because of her situation.

But I think this comment is a bit much, she doesn’t have to be delighted to be an aunt again when she’s grieving having her own child.

OrangeTrees7 · 21/08/2026 14:44

I can only speak from my experience. I was in the process of medical management of a missed miscarriage, my second that year, whilst my sister gave birth, my first miscarriage was due 3 weeks after her. I never once resented or felt she should pander to me because of my situation, I saw it as a joyous occasion and my issues with fertility were seperate to becoming an Aunt. I think this is your sisters cross to bear and not yours, you can feel for her but do not dampen the joy you all feel having a new baby.

This, it must be torturous being around people who can easily conceive when you are desperate to have a child yourself.
Perhaps more so with family.
Cut your sister some slack.

OneNaiceSnail · 21/08/2026 14:45

She’s being ridiculous and I’m surprised so many people would be truly fine with what she’s said. You’ve kept hurtful things you’ve thought to yourself, so should she. If it’s too difficult to her and she wants to step back, then that’s fine. She could do it without the vile and spiteful comments though, you’ve not done anything to purposely hurt her

No personally I do not like the idea of surrogacy but also believe in woman having a choice to do what they’d like.
