 The letter 'N' is what you need,

 When you take a nap,

 Need to put your nightshirt on,

 Or put on your nightcap.

 'N' begins nummies,

 Which are really nice to eat

At night before you nuzzle down,

 In between the sheets

'N' goes:

NNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNN

'N' goes:

NNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNN

 When you want to rest your body,

 Lay your noggin down.

 Put on your pyjamas

 Or put on your nightgown.

 Tell your niece and nephew

 And the neighbours down your street

 The letter N is really helpful

 When you need to sleep

And 'N' goes:

NNNNNNNNNNNNNNNNNNNNNNNNNNNNNN (x 4)

''Nighty night!''
