How to muffle or sound proof kids outside constantly hitting home

Hello everyone! First post here. I’m scared this is not the right spot but I can’t find a sub that’s seems better
Okay on to the point!

Is there a easy non construction ( also kinda cheap) way to block out the noise and force of kids “playing” and hitting our trailer?

2 years ago we moved into this manufactured home and it sits at a “trailer park “

And I have regretted it since week one.

The people to our right side, shortly after moving in became the on site managers.
They have 4 kids ages 4-12

The kids throw things(balls, small toys, full bottles of water) at my home to the point we’ve had 9 pictures fall off the walls.

My kids are miserable. They’re toddlers and think it’s time to go outside every time they hear the kids outside

We can’t really just throw the money away that we have paid or we would just move. It’s rent to own and the down payment was a big deal for us.

We have have asked the kids and parents to stop be more careful etc, provided videos of the kids hitting our house and windows with full bottles of water.
Emailed the owners of the community.
Nothing helps so I’m trying to just help the sound

Thank you to everyone that has read this long babble
