This really isn't about being a teacher or not.
I didn't work for almost 5 years, and had 2 DCs with a small age gap.
I never even thought about the benefits of 'having an H who was a teacher'.
I do wish OP that you would actually analyse what you want from your thread.
No one would disagree with having to care for a 1 year old and a 3 years old all day is tiring. But some of us did that for years. Mine didn't go to nursery or anything till they were 4, as there weren't any around at the time (my children are possibly your age now.) I had them all day every day for 4 years.
I'd given up a professional job to be a SAHM as that's what I wanted to do. I was an older Mum too.
Yes, it was hard.
Very hard, with long distance family.
But I did manage to have time to myself by handing over to DH at weekends, even having short holidays going to see family.
What is it that you want?
It appears to be a moan, which is fine.
But if that's all it is, at least say so.
