Science Says That Having Kids Ages Mums By 11 Years

I know what most of you are thinking after reading the title of this blog: “Only 11 years?! My kid could age me that in one week of school holidays!”

The science

In a study released earlier this year, scientists from Virginia’s George Mason University reported that women who have given birth appear to age faster biologically than those that are childfree. The difference on a cellular level was equivalent to around 11 years.

The study of 2,000 American women aged between 20 and 44, found that the length of telomeres were shorter in the mums than in the childfree women. Basically, telomeres are a compound structure at the end of a chromosome. Each time a cell divides, the telomeres get shorter. When they are too short, the cell can no longer divide and the process is associated with aging.

Of course, this is only one study and scientists admit that they need to do further research to understand why this occurs. But I reckon I can pinpoint how those 11 years of extra aging came about. It’s probably down to these very special “mum moments”:

Pregnancy = 2 years of aging

Nine months of morning sickness, back ache, tender breasts, and bladder bouncing, along with every other little niggle that pregnancy can bring, is definitely worthy of a large chunk of the total years of aging.

The birth = 1 year of aging

Like, do I even need to explain this one!

Sleepless nights = 2 years of aging

The first month of my first born’s life is a complete blur thanks to the jarring realisation that I will never, ever sleep the same again. The second month I remember way too vividly thanks to colic!


Feeding battles = 1 year of aging

Whether you’re struggling with attachment issues, a distracted baby, or trying to focus your eyes to measure out formula correctly at four in the morning, it all adds up. Once they’re on to solids then you’ve got those awesome dinnertime battles to look forward to!

The first poonami = 6 months of aging

If it happens at home, count your lucky stars. If it is out in public, add on another six months! The one that required me to undress my baby in the bath was a life changer.

Leaving the house with a newborn = 6 months of aging

Once you’ve packed everything bar the kitchen sink, changed the baby three times and fed them twice, just remembering where the keys are can be more mind-wrenching than long division. Speaking of which …

Helping your kid with homework = 1 year of aging

Whether it’s guiding them through those first readers (which, we might add, are not great page-turners!), trying to explain the complexities of the English language (it’s not worth it), or trying to recall the processes for long division (Google is your friend), it will all give you a profound sense of appreciation for teachers.

First day of school = 1 year of aging

The realisation that your baby is growing up takes a toll on mums. You’re gonna need so many tissues!


Never going to the bathroom alone again = 1 year of aging

Explaining to your toddler that you have gone to the bathroom and will be out in two minutes, not entered a portal into another universe, is a conversation that you will have over, and over, and over again.

First night away from your kid = 6 months of aging

Are they OK? Are they warm enough? Are they too warm? Are they hungry? Did they eat too much? Should I call? Why didn’t they call?

Family holidays = 6 months of aging

It’s supposed to be a holiday – for everyone! But parenting doesn’t stop just because you left the house. In fact, it gets downright harder because you now have restless kids, unfamiliar surroundings, forgotten essential items and a massive hole in your bank account.

Total = 11 years of aging

So there it is. But as much as our kids have the ability to age us, I’m sure parents would agree – we would give any number of sleepless nights and grey hairs just to see our kids happy and healthy.

By the way, the first time you give your teen a driving lesson … there’s another 11 years right there!

    I had a little hard time doing the adding but now it makes me feel there are other things that can possibly cause ageing just from being a mom and I’m sure having twins or multiples might double the figure, right? And P.S. I always need a holiday from Family holidays.

    Yikes! No wonder I feel tired so often lol. 2 kids – 22 years of premature ageing! Crikey!! Though in saying that, kids to keep you young as well. They do this by playing with them, enjoying the laughs and simplicity that being a child brings.

  3. Shelz69 29/10/2018 at 8:39 pm

    lol that is so funny. I think it might be a bit out though as I feel like its aged me 20 years. I certainly think the sleep deprivation is a key issue but I also believe it has all been worth it and I’d do it all again.

    This is hilarious!! No wonder I feel so old! Im glad its noy 11 years per child, I would be 107 years old…. I don’t look a day over 99

  5. felicity beets 27/10/2018 at 1:37 pm

    I would definitely believe this although I think for me it is mainly the sleepless nights and teething.

  6. MuddledUpMolly 23/10/2018 at 10:02 pm

    OMG this is a depressing read as I am currently pregnant so feel even more years piling on top of me! I must admit that I do feel older and a bit more weathered since having children but not for one minute would I change that for the world 🙂

    Haha this made me have a wee giggle. I was like omg 11years. Holy hell no wonder I use anti aging cream and have since 25years old 😂. I can see all of the above definely does put alot of stress on one mum but I’d hope I’m not looking 11years older with it all 😂

    Haha this makes me laugh sometimes I really do feel like this especially everything you go through having kids and all the worries. Trying to do homework I just want to give up some days and sleep less nights still continue as they get older this does not surprise me at all.

  9. Bevik1971 15/10/2018 at 12:51 pm

    Haha OMG – no wonder I feel 90 most of the time!! I have a 25 year old son and an almost 6 year old daughter so I feel old anyway! I am not far off 50 though (according to this study I’m probably not far off 60) I’ve also got hip dysplasia and need 2 new hips so that doesn’t help! I still manage to work full time though! I’m getting my first hip replacement in about 5 months so I’m hoping I will be more mobile and can do more with my daughter 🙂

    Oh dear. Do we know if it’s 11 years in total no matter how many children or if it’s per kid? My eldest is 11 so technically I have aged 11 years since becoming a mum. But yeah my child free friends do seem fitter and more driven and focused! RIP all my joints and muscles 😉

      According to another study, it doesn’t matter how many kids you have so it’s not the birth that’s causing the aging, just being a mum!
