Mmmm so you are doing all nursery drop offs and pick ups, all night wakings, virtually all of the cooking, virtually all of the cleaning and all of the food shopping. Do you do the laundry too? And the majority of the childcare when your four year old is not at nursery.
I think the replies you get on Mumsnet are never very sympathetic to sahms tbh! And frankly I am surprised at the low expectations people have of their dh’s on the domestic side of things. It not occurring to your dh to see to the bin or empty the dw before work is not something to be celebrated!
Presumably men who are single manage to look after themselves and do some domestic chores?
Tbh I think you are both doing a lot. Part of it is because you are in the very worst of the parenting trenches atm. Things will get better gradually but not for a few years yet. This is a marathon so your arrangements need to be sustainable.
My dh has a seriously big job too but in thirty years he has only stayed up until 1 or 2 am working about three or four times when there was a dire emergency. And he managed to do a lot more around the house than your dh does.
For a start he took over the cooking at weekends and cooked Sunday lunch and either got us a takeaway on Saturday night or put together a fakeaway type dish. He always did a food shop during the week too. Mind you he enjoys cooking. He would also take the dc out by himself for a weekend morning or afternoon so I could catch up on sleep,
My point is that you both decided to have dc and the dc are both of your responsibilities.
So I think this is about time efficiency as well as hours by the clock. Your dh is a family man now, he can’t expect to continue to work in exactly the same way he did before you had children. Him going to bed so late has a knock on effect on you all. He should be able to do a reasonable job within a 7 am to 7 pm time slot. Can he work during his commute on the days he doesn’t wfh?
On your side, can you tackle why your 18 month old is waking every night for an hour? Are they hungry? Can you give them an extra feed or snack before bed? They could be going through a growth spurt? It is reasonable to expect them to be more or less sleeping through the night at this age. I know it’s not always easy but don’t allow that to become entrenched. Sleep is so important.
And why is your four year old having meltdowns in the morning if you are not there? Surely this is a sign that your dh is not involved enough? Sorry but you simply both have to power through that as a couple until your four year old is equally comfortable with both of you. It may be difficult the first couple of times but it isn’t going to improve if you don’t try.
The key here is working smarter not harder and sorry, unlike everyone else on here, I think your dh could share more of the domestic grind at weekends and he definitely needs to sort out his work hours. Sometimes just swapping roles is a rest!
So I definitely agree with pp too op that you should start gradually preparing for when you go back to work, if your health condition will allow this, so that these patterns don’t get too entrenched, and your domestic and parenting tasks and earning capacity, get split more equally in future.
