They will be dealing with school letters, bake sales, dress up days, poorly small people sent home, packed lunches, homework and after school clubs as well as taxes, accounts, sales, marketing, outsourcers, coworkers - oh, and the actual work that you charge for.
One father I talked to told me that it is the overwhelming responsibility of becoming a parent which tips some men into depression. Do fathers, and gay fathers in particular, feel this responsibility more than mothers?
If your child is a digital native immersed in their games, messages and photos, going back to school and into the classroom can feel like a retrograde step. School, in an ideal world, is the environment for our children to learn and create.
This morning my four-year-old walked in on me in the bathroom and caught me mid-diet, eyes downcast with a frown on my face. She followed my gaze and immediately took in the silver scales I was standing on in the middle of the floor, out from their usual hiding place in the cupboard. "Mum, are you measuring yourself?"
When it was 6pm and they'd both refused their dinner and watched TV instead, there you were. When it 10am and we'd missed playgroup because of tantrums and I couldn't get the timing right to leave the house, there you were.
Starting school has been discussed, analysed and mulled over since kids first went into education. There are articles, blog posts, forums and books on the subject. You can disappear up your own bum reading them all - believe me over the summer I nearly did.
Let's go right back to being pregnant with my twin girls, vomiting into a newspaper on a train as I headed down to a client meeting 4 hours away. Or, let's take a peep at me editing copy for a magazine using my smart phone from the maternity ward whilst nursing two babies.
Last week a colleague and I travelled to Greece to the annual EECERA Conference. I like to attend such conferences because I believe that if we do not work to connect practitioners, policy makers and academics then we will never gain the coherence we need to ensure policies and practice are effective and actually support children and families in a way that also supports social justice.
Before they go to uni take your son or daughter to the supermarket with you and get them to do the weekly shop on a budget that will be the same as they'll be on at university.
Good news; today's teenagers are less likely to drink, smoke and take drugs than their predecessors, according to statistics from the Department of Health this week. This, it would seem, makes them the most sensible, healthy and fresh-smelling generation for a decade.
No "Well dones you donated good genes", no "How are you feeling?" and no offers of advice on how to fathom out the bewildering world of fatherhood. Instead, they are left to figure it out for themselves, hope for the best and then get themselves back to work.
When you go to the doctor to talk about 'feeling a bit down' they get you to do a Depression Questionnaire - like one of those multiple-choice quizzes you get in magazines, only not as fun. Just check 9 easy tick boxes for your chance to win a prescription for legal drugs and a leaflet on 'talking therapies'. #winning
My youngest child attends the British International School, Phuket. I must admit, I gulped a bit when I paid the school fees. But so far, I am fine with what I am paying for. It costs a lot to run this little piece of Great Britain in the tropical paradise of Phuket, and the money has to come from somewhere.
I'd love to ban the term 'chemical pregnancy'. It's a confusing phrase and many women misunderstand what it means - if I had £1 for every time someone's asked me to explain it I'd be very well off.
If we accept that birth has become a multi-billion dollar business around the world, then all expectant parents are consumers of that business.
