You've decided you want to have kids.
You have decided with whom you want to have them.
They are willing to have kids.
If they are a man, should you check that they will support you through pregnancy, birth and early years, and look to see if they are supporting their other children, if any?
If they are a woman, should you check how well they - and any previous partners - are supporting their existing children.
Should both of you look to see how well you can support your children, before looking to benefit support?
[FWIW, I have 2 children with XW; DS & DD both adults now, though in education. I have, quite rightly, spent scores of thousands in supporting both of them to adulthood. XW & I were both professionals; both worked bar XW taking about 18 months out of work late pregnancy early years.]
