From my perspective, DH and I both work full time and whilst I cook a lot (in advance so there's always something for the kids when DH brings them home), we rarely eat as a family during the week.
I've made a point of sitting down together as a family for either breakfast, lunch or dinner at least 3 times over the weekend (so Friday evening, Saturday lunch, Sunday dinner for example) and I'm strict about no screens at the table when we're all together.
My kids are skinny things and don't seem to have huge appetites so I don't ply them with snacks and if they're fussy about eating something, I run them ragged outside or in the pool and then present them the same meal. Usually they're so hungry they'll eat anything. I also teach them to eat with their mouths closed, no elbows on the table and using a knife and fork. These are basic table necessities that I think will help them later in life.
But yes, clearly if I was home earlier I'd have dinner made for us all to sit down to when DH and the kids get home, but it doesn't work like that at the moment so I work with the time we have. It helps that office/home/school is all in the same 4 mile radius so no commute.
It's hugely difficult for parents these days, where the costs of childcare are horrendous for most especially in the UK - in the space of one generation, we've gone from having one parent at home being the norm (and affordable) to both parents having to work (not to mention wanting too which is a perfectly valid reason too, I love my career) to be able to afford to keep a roof over their heads.
