Some nights Im so mentally and physically exhausted by work and house admin, I dont even brush my teeth

Poor millennial dads. According to a study just published, 42% of fathers born after 1980 feel burnt out most or all of the time from the strain of trying to juggle their work and family lives. This compares with 0% of men born between 200,000BC and 1980, who werent expected to share childcare and domestic duties at all, and were allowed to sit around in their pants after work, ignoring their children, reading the paper and being handed things. Even family men with stressful jobs who you would think would feel the strain, such as Stalin and Mussolini, never felt burnt out. Maybe if Mrs Stalin had put her foot down and forced him indoors to pull his weight around the house, push the vacuum cleaner round a few times or change the odd festering nappy, he wouldnt have had the energy to cause the deaths of millions of people. I know I wouldnt. Some nights Im so mentally and physically exhausted by work and house admin, I dont even brush my teeth, let alone start drafting a forced collectivisation policy.

But hang on a second. Relationship experts are now saying that as many as 40% of people in long-term relationships will have an affair. And biological anthropologist Dr Helen Fisher quotes research that shows 56% of men whove have had affairs described their marriage as being happy. What I want to know is, where exactly are these cheating men finding the energy and time for all this extramarital bonking? Surely theyre too worn out by all the womens work theyre doing: ironing name tags on to school ties and sports socks, scrubbing the toilet before the cleaner arrives, arranging play dates, choosing presents for their wives extended families theyve never met, shining torches into their childrens bottoms and checking for intestinal worms, combing lice eggs out of their hair, baking cupcakes at three in the morning, crawling around on their hands and knees on the kitchen floor with a dustpan and brush wondering where all the peas and glitter came from, and being passive-aggressive to tiger mums at the school gate? I have done all of these things before 9am on many occasions, and the last thing I want to do afterwards is indulge in some lying, hiding and fornicating. I think I speak for all women on that one.

Of course the real story here is not that a new generation of fathers are starting to feel the work/life strain that women have for years, but that they hadnt been feeling it until now. And that while its great that todays new dads are keen to divvy up childcare and domestic responsibilities, the infrastructure desperately needs to catch up. We still dont have affordable childcare, and while most employers support the governments shared parental leave policy, a recent study showed that only 2% of fathers are taking this right. Compare this with Sweden, where men take an average of three months off to care for a newborn. Here, less than 10% of men take more than the statutory two weeks.

And some of them are apparently still managing to fit in seeing another woman. I know that my own husband would love to have an affair, and I would love him to have one, too, but he simply doesnt have the time nor the energy. By the time hes got in from work, run a duster along the tops of the door frames and emptied the dishwasher, he barely has the energy for a quick catch up on hegemonic epistemology in feminist discourse before crashing out.

Also, we live in London which is a nightmare for parking, so whoever he was having sex with would either have to live in the same zone, or keep applying every month for their maximum allowance of visitors parking vouchers. Now I like sex as much as the next feminist, but even the possibility of a forbidden liaison isnt enough to entice me down to Hackney parking services once a month, to take a ticket and wait. Not after having done exactly that for the builders for 10 months. None of whom, incidentally, showed the slightest hint of being sexually attracted to me, not even the old ones. Its absolutely outrageous. And, if I might add, completely unprofessional. Perhaps we are making progress after all. Either that, or Im not ageing as well as I thought I was.
