We've had different phases:
Pre DC - both got in around 6, 6.30, maybe one of us went out for exercise, cooked and ate around 8ish.
Small DC - got home after nursery pick up around 6.15, DCs had eaten at nursery, snack and milk for them before bed about 7.30, we cooked and ate around 8ish
DCs at infants school, I changed to school hour working, all ate together 5.30 onwards, shifting to 6.30ish as they started after school activities.
Late primary school / early secondary school - activities all shifted to after dinner and DH and I both started exercising more regularly too in the evenings, back to eating afterwards about 8 or later, or some eating at 4 because eg swimming training 7-9. Got a bit random and couldn't always eat together.
Late teens (now) - on any given night usually a couple of us are out at sports/exercise early evening so still eating late but we don't always eat together either, the DCs sometimes cook eg pasta meals for themselves while we have something else, or sometimes someone will just have an omelette or similar.
We all go to bed fairly late now, 11 onwards, I get up around 6.30 most days, the others a bit later so it works just fine for us, we are all night owls but I'm a bit lark as well.
