A Man’s guide to baby growth during pregnancy

Now for those of you dads (and mums)-to-be who have downloaded one of the many pregnancy Apps on the market today, you will no doubt have come across the numerous baby growth size charts, which set out how large our bundles of joy will grow over the next 40 weeks – by comparing them to seeds, fruit and vegetables.

While the baby growth size charts start off simple enough, from blueberries and strawberries to avocados and mangos, before long they venture into the rarely sighted and often bizarre ‘exotic fruit aisle’ of your local specialist greengrocer.

Now, I’m all for healthy eating (although my wife might disagree) but show me a man who knows the relative size and dimensions of a dragon fruit versus a winter squash and I’ll show you a pink unicorn that poops gold. 

So to make things easier, I’ve created the definitive man’s guide to baby growth over the next 40-odd weeks of gestation, using universally recognised man-friendly items (granted, with a slight UK bias!).

    I really enjoyed reading your post. I thought your post was beautifully written

      12th October 2016 / 5:05 pm

      Thanks Lynda! That’s so sweet of you!

    This is all sorts of brilliant. As dad of three, I know the anticipation when my girls became the size of a regulation football far outshone even the build-up to the World Cup. Glad to have been directed here through Eric’s Sunday Share.

      Thanks buddy! Have just reached football size for our own growing baby, so I couldn’t agree more!

    Mwahaaa this is awesome. My partners size guide was ‘is he big enough to come out yet’? The testicle comparitive has still got me giggling. Loving your writing style! Fab post #bloggerclubuk

      Haha – thank you! Yes, the 12 week testicle is rather contentious! Was fortunate enough to have my Man’s Guide turned into a greeting card by an awesome card designer recently, but she couldn’t bring herself to draw the testicle (so it’s a battery on her version)! Thanks so much for your comments – always really appreciated!

    Hahah I much prefer this version! Who even knows how big a spaghetti squash is anyway?

      Haha – couldn’t agree more! Glad you enjoyed my man’s guide!

    Yup, I really struggled with the fruit thing, just didn’t help me at all. This is a fab alternative #TheList

      Ah thanks so much! Follow me on Instagram if you can, as I’m about to post something really cool related to my man’s guide…

  6. 7th March 2016 / 4:53 pm

    This is a much better way to show how big baby is haha!
    Thank you so much for linking up to #justanotherlinky

    Haha this is hilarious – albeit very useful. I am all for anything that helps Dads connect with pregnancy and beyond. Could have done with this chart a few years ago! Kathy x

    • 4th March 2016 / 4:31 pm

      Thanks Kathy – glad you like it! Took me bloody ages to make!!

    This is brilliant! Honestly I don’t know the sizes of the items they list either – I always had to google them to see how big they are! Love the rugby ball as the final baby! #FamilyFun

        Ouch for sure! Just popping back over to say thanks so much for sharing with us at #bloggerclubuk x

    This is brilliant – I remember when I was pregnant and reading the guides that compared the baby’s size to a fruit, there was often a confusion as to how big that fruit actually is! I mean, there is a lot of variation in fruit sizes! Thanks for posting #FamilyFun

  10. 26th February 2016 / 8:50 am

    Uh hello, this is amazing! I’m sending to my partner right now…I’ve already had the baby but it’s hilarious. Especially Week 12, I would have loved to say to people, he’s the size of my boyfriends right testicle! I had a boy so throughout the pregnancy I kept saying, “uh yea I have a penis inside me….’ ha ha! Pregnancy is already somewhat awkward, so why not make it fun. : )

    Reblogged this on and commented:
    Ha ha! A more simple way to understanding baby’s size in the womb….

      Thanks for sharing!! Glad you liked it!

  12. 25th February 2016 / 9:31 am

    This is brilliant…but I do expect that, in week 12, you will tell at least one random person you meet that your baby is the size of your right testicle!

  13. 22nd February 2016 / 9:22 am

    Haha good work mate, really like the chart. I remember going through this and writing about what the hell some of the fruit was. I still have no clue to this day!

    • 22nd February 2016 / 10:44 am

      Thanks buddy – hopefully it will become an invaluable source for new fruit-phobic dads like me!

  14. 17th February 2016 / 4:19 pm

    This is absolutely BRILLIANT! I love it and so true my own hubby would definitely agree with you. Thanks for linking up to Share With Me. #sharewithme

    • 17th February 2016 / 4:53 pm

      Thanks Jenny! Hope your husband likes it!

  15. 17th February 2016 / 10:25 am

    Absolutely brilliant! I actually think I relate to it better than the usual lime, lemon, melon ones! Best one has got to be the left shoe – lol. Thanks for linking up #FabFridayPos

    • 17th February 2016 / 10:38 am

      Thanks Sarah – I was particularly proud of that one!!

  16. 13th February 2016 / 7:46 am

    Ha ha I’ve often thought the same thing and wondered who thought those random fruit up?! My youngest is 3months so no more pregnancy apps for me now 🙁 I will miss them! #fridayfrolics

    • 13th February 2016 / 8:46 am

      Ah, thanks! And congrats on the new babe!

  17. 13th February 2016 / 1:30 am

    I so wish I had this when my kids were in utero. This makes way more sense than avocados!

  18. 11th February 2016 / 3:11 pm

    Wow how long did this take to do? Pretty impressive, and also entertaining!! Thanks for linking up to #coolmumclub love this!

    • 11th February 2016 / 3:28 pm

      Too long! Slow day at the office lol!

  19. 11th February 2016 / 1:11 pm

    This is excellent, certainly a change from the normal NCT facts. Thanks for sharing.

    • 11th February 2016 / 1:22 pm

      Thanks mate! Hope other expectant Dads get a kick out of it too!

  20. 9th February 2016 / 6:41 pm

    Oh my – laughed so hard – this is great! If only I had it when I was pregnant!


  21. 9th February 2016 / 1:01 pm

    I love this post! I have seen my fair share of size comparison charts. I’ve even seen ridiculous ones for example, ‘Your baby is 110th of a watermelon etc. Why even bother? This chart is funny, but also very useful! So thanks for sharing!
