Interesting observations.
I have 6 children, due to religious reasons, but after a tumultuous past few years, am no longer religious and have divorced their father. I work in a position that allows me to work from home (before pandemic) and so my ability to earn hasn't been affected.
The dc coped well over lockdown, with each other. That was an unexpected benefit!
They are of various ages, and the older ones do help out from time to time, but it's a rarity. They all have chores, they have enough food, a big enough home, and enjoy extra curricular activities in normal times. I would say they are pretty well adjusted overall, and anything they struggle with isn't exacerbated by having more than the average number of siblings, but by external forces that we couldn't control.
Judgements don't bother me, because I can't exactly unmake the decision to have six children, so I just move forward and do the best I can for them. Just like any other parent.
