My wife attends one shiur at the beginning of the evening and then goes to sleep.
My oldest daughter (who has been throught midrasha and is now in Tzahal) stays up all night, learns, and then davens with the early minyan.
My second daughter (second year sheerut leumi) does not stay up at all.
My third daughter (ulpana senior) stays up all night, learns, and then davens with the early minyan.
I am proud of both girls who stay up because they actually learn all night – no hanging out or walking about in the streets through the night.
