If you want this choice position   Have a cheery disposition   Rosy cheeks, no warts   Play games, all sort   You must be kind, you must be witty   Very sweet and fairly pretty   Take us on outings, give us treats   Sing songs, bring sweets   Never be cross or cruel   Never give us castor oil or gruel   Love us as a son and daughter   And never smell of barley water   If you won't scold and dominate us   We will never give you cause to hate us   We won't hide your spectacles so you can't see   Put toads in your bed or pepper in your tea   Hurry, Nanny   Many thanks sincerely   Jane and Michael Banks
