This is interesting - the only heated discussion my DH and I had was over life insurance for me, when the children were young. I explained that in order to continue to do his job and further is career in the event of my death, he would need a comparable life insurance policy to his own. Our kids were 4 and 1 at the time and he scoffed. Even his dad wasn’t brave enough to do that. My DH also travels continually for his job and in the present month will only be home 6 nights this month, barely scraping it in from the airport on DS’s A level results day. I may have torn a strip off him over that as there is not much I ask him to block his calendar out for.
Anyway, I explained that nannies generally only work 40-48hour weeks, so given he leaves the house at 6am and doesn’t return until 7pm when not travelling, he would actually need 1.5 permanent nannies to cover his working week. Given he travels much of the time, he would need overnight nanny care, so this would mean an on call night nanny. (So 2.5 nannies, with night time rates for the overnight work). I also explained that nannies, unlike aupairs, do not do laundry and housework. Given that they also need holiday , so would likely sub for each other, they nonetheless might not be able to do sick cover, so he’d need to have a paid subscription to an on-call nanny service for evening/night and sickness cover. Nannies do not work when they are sick, so if your kids get norovirus consecutively and then their carer gets it [ie usually me] you need someone immediately. They will launder the kids clothing and prepare their meals, and tidy their rooms, but they generally do not touch adult laundry or household cleaning, nor do they do the online shop or school related admin. They don’t wait in for the British Gas repairman when it goes caput or needs servicing, they don’t pop to the drycleaners or take shoes to be resoled etc. They do not have legal consent to represent you as a parent should one of your kids fall over in football/iceskating, breaks an arm and need to go to hospital for xrays and surgery… they can’t help. So he would need a PT PA to do all this - or quit his job for a family friendly role.
So on the back of an envelope, given my DH was not actually as senior 17 years ago as he is now, we worked out that he would need about over £100k back then to hire in the services that I do for free, and allow for this to be spent over over about 8-10 years. It cost almost as much to replace me as he was earning at the time. His family live 4hours drive away so not exactly near in an emergency.
He took out life insurance for me, though. It may not be ‘skilled’ work that no-one else can do, but the issue is that SAHM’s are present, adaptable to any task required, and legally responsible for 24 hours a day, seven days a week, even when sick, because they are not bound by employment law. Paying other people to fulfil that function costs a fortune.
