Fine’ish. I doubt it’s healty to grow up knowing your mother isn’t there because she’s in prison.
They'll be fine. Lots and lots of kids have it actually hard, because their mom is sent away when they're 5 or 6. Here? No problem. I think she's a sociopath, but her family planning decision makes perfect sense, and the people writing comments about how callous or irresponsible she is are telling on themselves in a particular weird way.
