I can't eat when i first come home from work, so we have a late dinner (about 7) - DD has a two stage lunch - one bit before her nap (around 12), one after (she naps around 1230 and eats around 3) - so it works much the same as the two stage dinner MD described. if we try and eat at different times, or miss that broken lunch, it messes with her and she is a nightmare to either get through dinner or get in to bed.

do what works for your family - that's what we do!
