*My OH has 8yo twins from a previous relationship.
Not married then?
We now have a baby and I’ll return to work 2 days a week when she’s 8 months.
OP presumably will be relying on OH's income.
I will work 1 weekend a month and this falls on the weekends OH has the twins (he has them every other weekend)
He has them two weekends a month.
- he’s unhappy that he will work all week then look after 2 children and a baby on his own for the weekend.
They're his children. He'll be on his own with his 3 children for approx 20 hrs a month.
He does a lot of travelling during the week and his job can be intense.
The big job. He probably gets to have spare time in the evenings to go to the gym and socialise while OP brings up their child.
He spilt up with his ex when the twins were 18months
Why did they split up?
and had them on his own at a “difficult age” they have of course become easier with age but he now has a really negative mindset of looking after children on his own
The ex probably looked after them on her own far more.
(I actually feel like they will be helpful with the baby) they are amazing with her now at 4 months and as they got older they will become even more helpful.
They are children - half-siblings not parents.
He wants me to look for another job saying there will be loads of opportunities out there where I won’t have to work a weekend but I don’t want to spend the rest of my maternity job hunting.
He could look for a job where he's home more. Why should you change your job because he can't be arsed to parent his children
Is it unreasonable for him to look after all 3 once a month?
No. They are his children. Two of them are not yours.
