If she was too lazy to ensure they went to school, you can guarantee she will be too lazy to make sure they are properly home educated. All she'll teach them is how to beg and grift for stuff online. If you want a great example of what happens when lazy, stupid people 'home educate' their children with zero effort just look at the Ingham family and how their kids are now completely isolated from their peers (and uneducated).
I think this will be terrible for both A and O. Of course they can still hang out with friends from their old school but they will grow apart as they'll be missing out on all the stuff that actually happens day to day in school. Meanwhile they'll be spending their lives online mixing with god knows who. Both those kids are very vulnerable to online weirdos due to their chaotic home situation
and tbh Ash wouldn't know what was going on as she's either not there or not involving herself with them.
