We have it lucky atm because DH gets home at 5pm so we eat around then. We are slowly moving the girls dinner back to hopefully be around 6pm when he will get home when we live in Sydney. We all sit down together. If the girls sit down differently to us (like if we are going out or want to eat something they wouldn't) we still sit down with them and have a drink of water or tea or something to sit and "do" dinner socially with them. They eat better when we are with them & we always chat about our day & what is happening the next day.
