Baby's First Morning/What Is a Baby/La La Lu

What is a baby?
 I just can't understand
 It must be something wonderful
 It must be something grand
 'Cause everybody's smiling
 In a kind and wistful way
 And they haven't even noticed
 That I'm around today
 ♪
 What is a baby, anyway?
 Oh, what is a baby
 I must find out today
 What makes Jim Dear and Darling
 Act this way
 ♪
 La la lu, La la lu
 Oh, my little star sweeper
 I'll sweep the stardust for you
 La la lu, La la lu
 Little soft fluffy sleeper
 Here comes a pink cloud for you
 La la lu, La la lu
 Little wandering angel
 Fold up your wings close your eyes
 La la lu, La la lu
 And may love be your keeper
 La la lu, La la lu, La la lu
