He's probably exicted that he's home after a long day, and can let out the energy that has built up all day! He probably is ready to play :)

Trampoline!!!
We’ve gone through (wore out), one kids model and two heavy duty exercise versions over the years! It’s definitely a stim (his neurologist said), great form of exercise! Just make sure you watch where it’s located, damn thing is a kid slingshot when they get comfortable using it and start going for height!

Thanks a lot! He has trampoline from 4 years ago but he doesn’t like it very much he just likes to jump on ground I don’t know whyyy!!

Trampoline maybe even a jump rope ? I loved jump ropes.
