Haven't watched/read for awhile and just looked at Emilia's birthday vlog.
Come 2-3 years, E1 will be the full and only parent of the younger three and will be expected to fully take care of them, if she isn't already. You can tell by the fact Jonathan and Anna seemed completely unable to in any capacity keep the younger 3 calm or in line, E1 did better then the both of them and I can honestly tell by her behavior that she's probably been doing that for a long time, I have no doubt that if their channel lasts until she's thirteen that she will be the only caretaker of herself and those kids, although, that implies that Anna and Jonathan ever were proper ones in the first place.
A lot of people say E1 is spoiled on this thread, but I think we should all remember that these kids are products of their parents (Anna and Jonathan) and E1 already seems to be doing better with her siblings and better by them, Anna & Jonathan's children, then they are, and while they are certainly spoiled re: finances, etc if they're doing better then Anna and Jonathan, they're already a step ahead.
I really do fear for when E1 goes into puberty and when E2 ends up as well, if their channel is still around, E1 will be infinitely sexualized (more then she, and the other 3 already are) and they WILL put on some show about trying to get Eduardo puberty blockers or estrogen, these 2 are borderline fetishists of their own children. Or when the two of them subsequently go into their teenager phases and start leaking everything going on in their house online or to their friends. For their own safety, cos neither Anna or Jonathan are going to take it lightly if one of those 2 is being genuinely honest about whatever goes on when the camera is off.
Luckily, I guess, the channel definitely will not be around long enough for the As to see the same treatment, but all of these kids deserved better and still do, as I don't even see it being around long enough for E1 and E2 to get into puberty or edgy teenager phases, but as long as even of the kids are with Anna and Jonathan; they will not be safe, online or offline. I have a restraining order against my parents, I wouldn't be surprised if all of them ended up with them against Anna and Jonathan in the future, lol.
