Interesting article.

1. It doesn't mention obvious potential causes to brain changes and hormone levels that coincide with having children like lack of sleep, changes to diet, or adjustments to work patterns etc.

2. It says towards the end that I should continue to wrestle the boys. Great!

0. Earplugs 1. Division-of-labor, specialization of trade... although it might not fit every feminists' "equality of outcome, share everything" political-correctness, it doesn't make combined net income much sense (or cents) to risk a $300k income with sleeplessness/low-productivity vs. an $80k one if one spouse (assuming spouse isn't a lawyer, doctor or engineer) can be at home full-time, or both as full-time parent…

This is the type of sexist, ignorant bullshit I'd expect to see on reddit. Welcome to hn

This is worse than reddit actually. Actually his comment is what I expect a subset of HN would think.

Male tech workers who value money above all else.

I can still remember "feeling" the change in everyday thought process once my 1st was born. It was so noticeable... like I'd just stepped into someone else's brain. really weird.

Are you able to elaborate?

Its hard to do so.

It felt like a mental "click" but not like you get when you have been trying to solve a puzzle... it felt like a mental " gear change ".

My thought processes changed order or priority, Things that I felt were important before were suddenly less important and I think I things from a different angle (not just life stuff but problem solving approaches.).

its really hard to describe.

What I can say is that having a second didnt do a damned thing... lol whatever change was going to happen only happened on the first.

I am sure the author means well. However, this makes little sense from an evolutionary standpoint. Although humans have evolved far more than most animals on this planet, the basic idea of evolutionary biology remains the same. In the wild, males have to hunt (provide food), protect the new born(s) and their mate(s) from threats. Therefore having the same level or higher levels of Testosterone is a biological imperat…

I'm not sure if being very aggressive is useful if you have a small child. Also, testosterone increase could lead to searching for new mates, thus lowering chances of survival for mother and child.

"Certain areas within parts of the brain linked to attachment, nurturing, empathy and the ability to interpret and react appropriately to a baby’s behavior had more gray and white matter between 12 and 16 weeks than they did between two and four weeks." For you father-programmers out there: did you notice any changes in your programming/work abilities around the 12-16 week mark?

Based on the replies, I jokingly conclude that the increase in gray and white matter during these baby phases is to handle the cognitive dysfunction of sleep deprivation. I wonder if sleep deprivation is related to raising children pre industrial era. It seems logical but I don't know much on this topic. :)

I just read Matthew Walkers book - Why We Sleep. It is probably a major factor in the changes.

Just watch the first few minutes of this.

>2014, Dr. Pilyoung Kim, Ph.D., a developmental neuroscientist at The University of Denver, put 16 new dads into an M.R.I. machine: once between the first two to four weeks of their baby’s life, and again between 12 and 16 weeks

16 examples -> I would set more store by tealeaf reading.

Looking into the T drop in fatherhood, the original study seems to account for self reports of 'sleep quality' but I wonder if sleep deprivation is not still a confounder in this finding. Annedoctally as a recent father of a 6 month old, I would likely self report a good sleep quality in a questionnaire. However, objectively I know I sleep about 5 hours 30min yesterday evening, which would be sufficient sleep 'depriv…

> Annedoctally as a recent father of a 6 month old, I would likely self report a good sleep quality in a questionnaire. However, objectively I know I sleep about 5 hours 30min yesterday evening, which would be sufficient sleep 'deprivation' to impact T production. When our 9 month old started to sleep through the night (at around 4-5 months), we'd get between 5-6 hours of sleep, which after the interrupted sleep of t…

Thank oh for being honest. There’s actually a topic on a different forum that is exactly about the taboo’ed negative things about parenting.

People refuse to see/acknowledge this, esp. women.

Earlier quoted context omitted.

>this makes little sense from an evolutionary standpoint I am certainly no expert on this area but it sounds to me like you are concluding that the study must be invalid, based on a bit of armchair science.

The ideas I have presented are not 'armchair science'. They're widely accepted in the field of evolutionary biology.

Evopsych explanations can often be used to argue both sides of any issue. For example, T is implicated in male aggression, which is useful when fending off predators both animal and human, but dangerous when you have a helpless, often extremely irritating Bundle of Evolutionary Fitness around. T is also thought to be involved in mate-seeking behaviour, which one may wish to downregulate for a while after successfully reproducing in order to devote resources to infant survival. Testosterone is also metabolically expensive, and those costs may be paid at the expense of the immune system. It might be advantageous to upregulate immune functions when an immuno-compromised neonate is around. You and the author could both be correct, but neglect important components of the testosterone fitness package.

> Women become pregnant before they become mothers. Men become pregnant after they become fathers.

I heard this joke a while ago, and while cruel seems to have an element of truth to it by observation. Lack of sleep, lack of exercise, less time to make healthy meals seems to be a terrible combination for weight gain.
