She was still bringing home good money w/ 1 kid in daycare, but maybe not 2. She quit like a year ago though, before she found out she was pregnant and from what I understand, before they were even trying.
PP here: This is why I have no sympathy for them, and why you don't need to. They knew their situation and decided to go for broke (literally). So you are fully justified to be disgusted that she's registered for nice stuff for #2, when she clearly has the essentials and put herself in whatever financial straits she's facing (and certainly doesn't have much respect for your in-laws, who are now starting over 25+ years later).
BUT, she doesn't live with you and it's not worth getting into a fight over. Gift card in an amount you think appropriate and be done.
