"Bounce to the beat" meaning in this context

Question

I was reading about acting out while saying a rhyme and I found this line:

Gently bounce baby to the beat.

Being a learner I suppose:

"Bouncing to the beat" is the same pattern as "dancing to the song"

Am I correct?

Now,

The word bounce generally means move back after hitting something.

I am rather confused as to what the bouncing a baby actually mean.

Please help.

Thanks in advance

Answer 1

The image is of a ball bouncing on the ground repeatedly. You lift the baby up and down, or jog them up and down on your knee, in time to the beat.
