1) Throw nothing away. (At the end of the story Tanner makes this his motto after accidently throwing away a baby.)
2) Always be prepared for the unexpected. (When they learn the at Kitty is expecting children Tanner has to go into a mad rush to prepare.)
3) Big things may come from small beginnings. (The baby they accidently threw away ended up becoming the most successful person in the family.)
