When I was pg with my dc I suddenly became obsessed with getting promoted at work. Then I worked till I was 38 weeks and took holiday as pay because I had the idea we might need the money when the baby was born.
But we had more than enough money and I had a really generous maternity package.
Now I wish I'd taken more time to relax before the birth.
So I'm thinking it must have been hormonal. HAve others had "financial nesting"??
