[Kip Russell]

I recently heard of a never-married over-40 woman who adopted a child (and had never in years past expressed any genuine desire for babies and children), and I wonder if it was for the same reasons.

Unless she stands to inherit a small fortune, that's a terrible "investment". Kids are expensive (or so I've heard).

Kids are as expensive as you want them to be.
Cloth diapers, consignment sales, breast feeding, homeschooling, teach them frugality & productivity, make them start a business & build a home before moving out - cheap.
Disposable diapers, new boutique clothing, formula, premium private schools, endless “educational” toys, new car at 16 - expensive.

Kids are expensive (or so I've heard).

But for those who want them, it's well worth it.
