About homework - state primary schools normally don't give out homework apart from a weekly reading book and some spellings for older children, some more serious homework might start when they are 10-11, but it's the kids' homework, not for parents.
My husband is the middle one of three, parents professionals who were so busy with their careers they only "saw" their children once a year on holiday, and Dad read them a bedtime story every night, that was it. PIL tended to work weekends and evenings (from the office at home), the kids were expected to play outside or entertain themselves, there were never any after school activities (not saying that it's good, just stating that it's not anything unusual in 3 and under kids families.) My husband thinks he had a happy enough childhood, though he admits he barely knows his parents, because their life was all about work, work, work.
Overall amazed by the stone throwing on this topic, who decided, that the kids have to have that-this and that and if they don't get it, they are doomed? Kardashians are also one homogeneous mass ;) and I read a quote from one of them that having lots of siblings is amazing, it's like having ready provided friends (or i think at least a good chance of having friendship through family, due to sheer choice).
Anyway, I know families with lots of kids who are amazing and inspiring, and some not so...two-three generations ago most people had large families, and it's not like people in UK become so much happier and fulfilled and better nurtured by their parents since the average number of children became 1.7 or whatever it is.
