What is this part? It’s from my young child’s new mountain bike. I don’t know where it goes or what it’s purpose is!

Derailleur cage, there are 2 screw holes right over your RD.
To add to the other comment:
This is not to be confused with the cage of the derailleur that holds the pulley wheels – think of it like an impact cage/bumper.
Not only will this help the bike not get the derailleur banged up, at some point this WILL bend and make contact with the derailleur, inhibiting shifting. When the derailleur is in the smallest cog in the rear, make sure this clears the derailleur. If it doesn’t you can give it a manual adjustment (grab it and bend it outwards a tad).
Thanks for getting your kid a new ride, I am sure they are gonna love it!
Derailleur protector. Totally optional.
Thanks everyone!
Protector for the real derailleur.
If, for any reason, it comes in contact with the derailleur body, feel free to bend it away.
Teach your kid to set the bike down on the non drive side of the bike.
