Throw on your leisure suit and platform shoes and take your baby on a stroller ride back in time to share the music, TV shows, toys, films, and fashion of the 1970s. Never mind "apple," "boy," and "cat"—your little one is ready for this playfully illustrated primer of 100 words from the era, like "ABBA," "Brady Bunch," "corduroys," and "disco fever!" Can you dig it?
