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 am around today. What is a baby anyway? Oh, what is a baby? I must find out today. What makes Jim dear and darling at this weight? La la loo, la la loo Oh, my little star sweeper I'll sweep the star dust for you. La la loo, la la loo Little soft fluffy sleeper Here comes a pink cloud for you. La la loo, la la loo Little wandering angel Hold up your wings Close your eyes La la loo, la la loo And may love be your keeper. La la loo, la la loo La la loo There now, little star sweeper Dream on!
