Madonna has to schedule time for her children.

The 49-year-old singer - who has a seven-year-old son Rocco and an adopted
two-year-old boy David with husband Guy Ritchie, as well as an 11-year-old
daughter Lourdes from a previous relationship - makes sure her hectic diary
is a balance of family life and work commitments.
She told Q magazine: "I have to eke out the time. One day I don't see my
kids much and the next day I make sure I do.
"You look at your calendar and you go, 'OK, this day's crazy. But OK, this
day I'm going to take my daughter to ballet. The next day I'm going to be
gone all day. So the day after I'm going to make sure I'm around for dinner
and bathtime.' "
