Parenting morphs over time and to suit individual families. I'll add that my dh is a workaholic and was rarely home before 9.30pm.
Up until DD was about 7 I was a sahm or part-time. Play dates at our primary were called "teas". Visiting DC ate with the hosting families children or the family - at ours, I fed the children, usually at 6ish. They had crackers, fruit, a little cheese/ham at 4ish because they were usually starving.
When they were about 7 and 10 I went back to work full-time and the au-pair fed and ate with DC and sorted the after school activities. Our au-pairs fared very well because often both dc were out at tea or an activity and I'd do the pick-up. By then ds was 11/12 and if he had after school sports training or a match - it involved teas.
Plays/teas tail off at 11ish ime and homework/sport/music take over. I was usually home by 6.30. We had Swedish au-pairs and they were all great cooks because in Sweden the "ready meal" culture wasn't a thing. They ate with the dc at 6ish and I often joined them and there was enough for me. Pizza, pasta, wonderful mincemeat pastry tarts with egg, meatballs, meatloaf and we all were converted to hardbreed.
I used to make something for DH and if he was home before 10 would sit with him and have a glass of wine while he ate.
As DS hit 13/14 (there was a year when he grew 8 inches) he needed food as fuel and they were too big for au-pairs and he would have a ready meal or pasta (I used to make big bowls of pasta salad in the fridge for him to help himself) before I made dinner for 7.30 (getting in at about 6.30).
In the late teenage years "teas" morph into "gatherings" where the dc seem to take turns in having about 8 teenagers round and playing music and laughing and breaking the odd window and from about 16 beers become involved. Parents generally order pizza and have ice-cream in the fridge and fruit in the fruit bowl.
Then they leave home and leave their parents to fend entirely for themselves. We tend to eat at 9ish because DH is still late home and nowadays I often am not home until 8pm. DD is at home presently and cooks on Thursdays - she eats at 7ish - we eat later.
At weekends we tended to eat together at about 6.30 (still do) because the dc usually had plans or homework to catch up on.
