Perhaps you could send her a concerned note, suggesting, since Baby has proved to be such a heavy financial burden, that there are many loving childless couples out there and that it's not too late to be considering adoption. That's one way the village could help.
That should put a stop to any begging requests, anyway.
This sounds rude - but I'm all for it.
Another thought is to just flat out say - please stop begging for help buying you a home and paying to raise your child. Get off your butt, get back to work and support yourself like REAL MOMS do.
Geez, some people just don't know how incredibly gimme piggish they sound, I know we say it's rude to call someone on their rude behavior, but really, here is one occasion where it should be allowed, even encouraged. Even if you do it anonymously.
