TTC and cousin's birthdays

58 replies

EskarinaWeatherwax · 20/01/2025 15:03

I've recently had the MMR vaccines (again, had them before but didn't have immunity) and now finally in the clear to start TTC. I know it's super unlikely but if we did conceive this month, my due date would be a day before my nephew's birthday & only a couple of weeks after my niece. AIBU to TTC this month or would we better waiting a cycle?

Obviously I know the odds of conceiving on the first month are slim and the odds of them coming on their due date are also slim but just wondering if others have taken into account cousins birthdays when it comes to TTC and potential due dates. I'm probably totally overthinking this as I think well this cycle would result in being close to niece and nephew's birthday, next 3 months are close to Christmas and post Christmas etc and there's just really no ideal time is there so maybe we should just go for it & see what happens.

Good grief - why would it matter if your child shared a birthday with a cousin?

AttachmentFTW · 20/01/2025 16:10

This is honestly one of the strangest posts I've ever seen on AIBU. What's the relevance of your MMR vaccine? Why does it matter if cousins end up with birthdays close together? Just give it a go and if you conceive first month of trying you are very fortunate.

Cousins birthday is irrelevant. Kids born in Sept-Dec have better academic outcomes. No one has a choice on when they manage to get pregnant, but if you could control it I'd be aiming for the end of the year

Who TF decides when to procreate based on the birthday of someone else! I’ve heard it all now.

MrsClatterbuck · 20/01/2025 17:23

I had a cousin who's birthday was a day before my ds. It was also a day after another cousin on the other side of the family. It all was fine.

DrEggman · 20/01/2025 17:26

People think about these things??

We’ve got five birthdays in one month in my family. Mine is the week after one of my DC’s.

Fetburzswefg · 20/01/2025 17:26

Totally irrelevant when their cousin’s birthdays are, don’t consider them at all. My nephews (one for each sibling) have birthdays one day apart and nobody has ever thought anything of it.

WhatNoRaisins · 20/01/2025 17:27

To be fair I can easily imagine some difficult people that would get arsey over a family member having a baby too close to their child's birthday 😅. It's still batshit though and I wouldn't factor it into TTC.

MissScarletInTheBallroom · 20/01/2025 17:31

No offence OP but that might just be the silliest reason I've ever heard for delaying TTC.

Wingedharpy · 20/01/2025 17:37

Really?
No-one I have ever met in my life has ever said at the arrival of a lovely new baby,
"You do realise don't you, that they must have conceived this baby while they were staying with us last Christmas/after the eldest sports day/at our wedding/during that snowy period when we were all trapped indoors".
Babies are (hopefully) made when they are made and arrive when they arrive.
Now, get on with it and good luck!

flotsomandjetsome · 20/01/2025 18:07

As PPs have said don't most families (as per the randomness of any group of people) have a load of birthdays bunched up and then months with no one??

We have 4 family birthdays in January, none at all in the summer, and actually amongst friends and colleagues five people on the same day.

okaynotokay · 20/01/2025 21:42

OP, I truly understand what you mean and I therefore planned my pregnancy in a way that didn't overlap with birthdays / anniversary on the three months period. I naturally conceived in the second month. So everyone has my DC's birthday party to look forward to after their new year's celebration.

Eenameenadeeka · 20/01/2025 22:19

I never even thought about considering cousins birthdays! Id try not to have a December baby though, Christmas time birthdays aren't the best.

Hohohoeyy · 20/01/2025 22:23

It took me a year to get pregnant with my first so I think you’re massively overthinking about something that probably won’t happen.

EskarinaWeatherwax · 20/01/2025 15:14

Sorry, chronic overthinker over here. I just know birthdays are a massive deal for our family. I feel like if we'd been actively trying beforehand and then were still trying this month that's one thing but choosing to start this month feels different.

There wouldn't be any birthdays to celebrate if nobody was allowed to focus on having babies! This is more important than family occasions. If all goes well there will be an extra family member to bring along in future. Don't prioritise anything else.

SnoopysHoose · 21/01/2025 10:27

You share a birthday with millions of people, you're being silly.

Greeneyegirl · 21/01/2025 10:31

That's so random. With my first it took us 11 cycles to concieve, I couldn't have cared if they turned up Xmas day I just wanted to be pregnant. Honestly if you want to put it off for the sake of a birthday youre probably not ready

AKettleOfDifferentFish · 21/01/2025 10:39

Good grief, this is completely ridiculous. How do you even know what the due date of the baby would be, anyway? It usually gets adjusted after the 12 week scan so even if you did conceive immediately the due date based on your last period is just an initial rule of thumb.

MsSquiz · 21/01/2025 11:00

My SIL has 3 kids, their birthdays are 14th, 15th and 22nd of the same month. DD1 was born on the 18th of that month.
It is what it is!

LiquoriceAllsorts2 · 21/01/2025 11:11

Do not put your plans on hold for these birthdays. So what if they have similar birthdays

GreenTeaLikesMe · 21/01/2025 11:13

Each of my kids literally shares a birthday with one of their cousins. I actually think it's lovely, and at least we all remember each others' kids' birthdays!

SapphireOpal · 21/01/2025 11:19

You're massively overthinking this. Even if your due date is between their birthdays, the chances of the baby being born on either birthday are fairly small. And even if they were, so what?

FuckoffeeBeforeCoffee · 21/01/2025 11:33

My brother and my son have a day between their birthdays. I hadn't considered this when I was trying because I'm normal. It's never been an issue - in fact, they love it.

Tillow4ever · 21/01/2025 12:22

In the space of 5 weeks in our family we have:

2 nieces birthdays
2 nephews birthdays
2 sons birthdays
Christmas
1 BIL birthday
1 sister birthday

No-one has ever worried about sharing the limelight - and 2 of them have the same birthdays (not twins - different families).

At another month in the year we have:

1 sons birthday
1 nieces birthday
2 mum's birthdays
1 dad's birthday

We literally only have 1 nephews birthday that doesn't fall into either of these 2 month periods!

You are over thinking it - if you fall pregnant straight away, people will be happy for you. And if they are close in age maybe you can save the cost on parties by doing a joint celebration if you do anything that's family only?

Good luck!
