For Filipino moms and dads, in this day and age, do you still practice the use of "po" and "opo" and teach your kids to do the same?

I plan on teaching my son as soon as he's old enough to talk. Other than it being part of our tradition of being respectful to our elders, it is part of our Filipino language. As much as i'd like for him to be able to speak good English (and maybe other languages and Philippine dialects), i'd also like for him to appreciate Filipino :)
