AIBU to be thinking about a 3rd baby at 40?

myotheraccountsa · 24/04/2025 08:46

Feeling really conflicted and want some outside opinions.

Original plan was always to try for a 3rd at 35 but career totally got in the way and then became 100% convinced 2 was right for us although DH always wanted one more.

Now however have hit 40 and have this unshakeable feeling that I'm going to hugely regret not having one more. Reasons being:

  • I am terrified of my 2 growing up and leaving, just don't feel ready for an empty nest and no child to base my life around
  • We have 2 of 1 gender and will always feel we never had that last shot at one of the other
  • My 2 keep saying they'd like a little sibling
  • My hormones that for years were firmly heck no to babies are suddenly telling me I want one.

But reasons against it...

  • I'm 40!! When baby is 10, I would be 50
  • There would be a huge gap (over 10 years) between my kids). The eldest realistically wouldn't even live here for most of babies life
  • I'd have to take a career break and at my age may well not get back to where I am now
  • Whilst we do have enough bedrooms, one is our study so we'd probably need a bigger house.
  • It would use finances that could be going on our other childrens' university education, helping them set up their lives etc
  • I'm a bit scared of health issues etc for both me and baby at this age, although I'm very fit and well

What do others think, is it just the pre menopause hormones talking or will I genuinely look back and regret it forever if we don't try?

I had number 4 at 40 with a significant gap. All went great, big ones are mad about the baby (11 now but still called the baby!!) and always have been. They're happy to babysit and help out.

No issues here, 5 stars would recommend

I was one of three in a similar situation and, now with my own teenage DC, feel very strongly that my parents should have stopped at two. They were simply spread too thin and seemed exhausted by the time I was in my mid teens, which wasn’t great as they still had a decade to go with my younger sibling. They had a child touring universities and a child learning to read at the same time! They got away with it as we were bright, well-behaved children but there were definitely times when each of us didn’t receive proper attention at a time when we needed it.

Lucia573 · 24/04/2025 14:03

Don’t do it! Sounds like the age gap is too big. We’ve really enjoyed the changing activities and travels you can share with your children as they grow into late teens/early twenties. With a younger third child we couldn’t have done that (and probably couldn’t have afforded to). Your children will benefit more from the extra money and time you have for them than they would from a younger sibling. I’m mid-fifties now and rather enjoying the empty nest!

Darkdiamond · 24/04/2025 14:00

I did it at 39 and am so glad I did.

MaltipooMama · 24/04/2025 13:59

I would have loved to have had three, I always wanted three but started late! I will be 39 when my second (and last) is born and although I could try again at 40/41/42 it could potentially leave me with 3 under 3 which I think I would struggle with. If I’d had my first two earlier though and they were already out of the baby/toddler stage then I would definitely be wanting a third

VickyEadieofThigh · 24/04/2025 13:56

I'm 9 years older than my (unplanned) younger brother. I have always adored him, though the impact on our household (we have a brother 3 years older than me who went seriously off the rails whilst my parents were trying to cope with the new baby) was quite major.. We have a great relationship - I have no kids -but am very, very involved with his two young adult daughters - but...

When I left home aged 18 to go to university, he was utterly bereft - so much so that he suffered quite serious mental health issues that put him in hospital. He went psychosomatically blind for several weeks.

I tell you this, OP - and you'll note that my post has a mixed bag of issues, because my relationship with my younger brother is amazing (though neither of us has anything to do with our older brother at all) - in order to indicate that what you see as "pros" may not work out the way you might wish. And the impact of a baby on existing, quite a bit older children can be dramatic.

Snoken · 24/04/2025 13:46

This is absolutely just your hormones trying to trick you into having another baby. You cons by far outweigh your pros list. For me it's also the age gap that seals the deal. Having just seen my two kids through the teen years and into adulthood there is absolutely no way in hell I would have been able to manage a toddler at the same time. It would have absolutely ruined me and my relationship with my older kids. Focus on the blessings you have been given already.

Pyjamatimenow · 24/04/2025 13:38

I’ve thought about but only in the context of wondering how best to protect myself from such a catastrophe. No thanks.
You’re romanticising.

ginasevern · 24/04/2025 13:34

I doubt that your existing kids will appreciate "a little sibling" when their currently harmonious life is up-ended by a screaming, pooing, feeding machine. Have they watched too many Disney films perhaps? They also won't appreciate a clapped out mother and limited finances when they need guidance and financial resources in early adulthood. What will a little sibling really mean to them once they've left for uni? You also run the risk of significant health problems for yourself and the baby. As for your DH wanting more - why? Is he really happy to go through all that again in middle age? He won't be the one taking the physical risk either, will he!

ChildrenOfTheQuorn · 24/04/2025 13:31

Your reasons to have a third aren't great. Maybe a puppy would be more appropriate - you get to choose the sex of that....

I'm 56 with a 14yo. Only child, so different scenario,but I'm posting to highlight the guilt I now feel. I just couldn't see how selfish I/we were being at the time. Now that hormones have settled, I can.

Why do you think so?

I’m sure your 14 year old doesn’t feel like that

Calliopespa · 24/04/2025 12:59

Rollofrockandsand · 24/04/2025 12:21

The 40 bit is a non issue. My concern would be balancing needs with the age gaps

And again, the 40 bit a non issue but spinning the roulette wheel for a different gender is problematic.

SlagPit · 24/04/2025 12:33

You'd be mad to do this. It's just your hormones talking. None of your reasons to go ahead are actually that good (sorry).

KimberleyClark · 24/04/2025 08:58

None of your pros are actually a good reason to have anotner

  • I am terrified of my 2 growing up and leaving, just don't feel ready for an empty nest and no child to base my life around

You’ll have an empty nest eventually anyway. You’d just be postponing it by having another child.

  • We have 2 of 1 gender and will always feel we never had that last shot at one of the other

What if No 3 is the same sex?

  • My 2 keep saying they'd like a little sibling

You don’t have a child because your other children want you to. It’s your decision.

  • My hormones that for years were firmly heck no to babies are suddenly telling me I want one.

Yes, it’s that last chance saloon wobble.

Agree

gattocattivo · 24/04/2025 12:24

It’s the age gap rather than the age that would put me off. Why start all over again when your children are heading into secondary school?

And the reason about not wanting your children to grow up and leave is a really bad one …. Children get even more interesting and lovely as they grow older and flourish into independence.

Rollofrockandsand · 24/04/2025 12:21

The 40 bit is a non issue. My concern would be balancing needs with the age gaps

lazycats · 24/04/2025 11:49

That huge sibling age gap would be enough to put me off.

BangersAndGnash · 24/04/2025 11:45

I wouldn't - not because of my age (I had a baby in my early 40s, all perfectly fine and happy) but because of the age gap.

Your kids' teens will be affected by a baby - family holidays and days out will need to be toddler and small child-friendly, and activities for teens restricted. Their big exam years will be against your need to support a young child.

The age gap will work against them being close - they older two will be at Uni and then gone.

You don't know how you will feel by the time your kids are ready to leave home - you may well be looking forward to more adult time, panning your long term retirement etc. And - young adults are still our kids, they come home, tell jokes, allow us to fuss over them....you are a Mum for life.

Eenameenadeeka · 24/04/2025 11:41

Hmm. We have a big age gap between our oldest and youngest, because we have 4. I adore them all and of course I wouldn't change a thing, but parenting preteens / teens at the same time as babies does have its challenges. Their needs are so different, it's not always easy to do a whole family activity, you don't necessarily want your older kids bringing friends around all the time because they might wake the baby.. you are dragging toddlers around to after school activities and sports . There are so many lovely things about their bond and having lots of children but it is also exhausting, and I had my last at 30.

itbemay1 · 24/04/2025 11:39

I wouldn’t but each to there own

Katemax82 · 24/04/2025 11:37

Do whats right for you, I had my 4th unplanned baby 6 weeks ago at 42.

TheaBrandt1 · 24/04/2025 11:09

Dont under estimate how you are likely to change during your 40s. At 42 I peaked and basically felt the same as I did at 35. However by 45 onwards I (and every other woman I know) feels very different. I would absolutely hate to be parenting a younger child now at 50. My caring hormones have drained away.

Also teens are full on even relatively easy ones. Far more expected of parents of teens than our parents did for us. We stopped at two and we frequently say how relieved we are we did. Plus paying for university.

I have a suspicion this is a dressed up ‘gender disappointment’ thread and I’m willing to bet the 2 kids are boys. I’m not actually criticising, but am I right op? Because if so that puts a different spin on things.

Maybe, life doesn’t always pan out the way we hope
