The parents seem to think that parenting is a pay-to-play relationship. LW would be wise to turn down the gifts that these people are trying to pour on her. I suspect, given the brother cutting them off and their frantic turn to LW, that everything they do comes with a halter or a noose attached, and they expect full return on their investments. I would not advise even having them to visit. The less contact the better.

Prudence gives such awful advice.
