What are the motifs in The Story of the Trapp Family Singers by Maria von Trapp?

Love fills every chapter of this book, although Maria doesn't use the word love to tie it all up until the book's conclusion. There is an immediate affection between Maria and each member of the Trapp family. Her love for the children made her outspoken regarding their lack of practical clothing. It could very well have been her love for the children that made her agree to marry the Captain.
