that seems to be the reasoning of most "local" parents. they put in long hours and if the kids went to bed early, they would not have any time to see their parents. as i said, i know many toddlers that go to sleep well after 9pm, some as late as midnight.
you really need to do what works for you and your family. just make sure that your child is getting enough sleep overall. most local kids have long naps in the afternoon until they start primary school. i believe this is so that they are able to stay awake later to play with mummy & daddy.
personally, i prefer my kids to go to bed early. it gives me some wind-down time and some alone time with husband before we go to bed ourselves.
