Just name your kids based on the rules. 
You get married to the love of your life and have your first baby 10 months later. It's a baby boy! You want his first name to be 6 letters long and his middle name to start with the same letter as the first.
2 years later, you have another baby! A baby girl this time. You want her first name to be a flower and her middle name to have a special meaning to you. (name of a parent, grandparent, etc.)
Then, big surprise, twins! A boy and a girl. They are identical and so you want their names to be unique. You want the boy's first name to be 5 letters long and his middle name to relate to your favorite sports team. You want the girl's name to be 4 letters long and her middle name to relate to your favorite place to visit.
Years later, you adopt a 10 month old baby from Russia. You want her name to be old-fashioned and classical. Very pretty.
Have fun.
