ASK: now convert that into a song for a 5 year old

----------------------------------------

ChatGPT says: 

Sure, here's a simple song about the importance of sleep:

Verse 1:
We all need to rest our heads
And go to sleep in our cozy beds
Regular sleep is the key
To feeling good and healthy

Chorus:
Sleep, sleep, the magic elixir
It helps us grow and gives us vigor
Don't stay up too late at night
Or you won't feel so bright

Verse 2:
Keep your room nice and cool
And your sleep will be extra smooth
And if you can't fall asleep
Get out of bed and don't make a peep

Chorus:
Sleep, sleep, the magic elixir
It helps us grow and gives us vigor
Don't stay up too late at night
Or you won't feel so bright

Verse 3:
Sleep is important, it's true
For our brains and our bodies too
We won't feel so good without it
So let's all just go to bed

Chorus:
Sleep, sleep, the magic elixir
It helps us grow and gives us vigor
Don't stay up too late at night
Or you won't feel so bright

Outro:
So let's all get a good night's sleep
And tomorrow, we'll feel so sweet
Sleep tight and have nice dreams
And wake up feeling like a new team!
