do a headstand

(Thats a pic of my little brother)
Anyway..
I do it on the wall about 10 times a day!
My little brother is 9 years old and he can do a headstand for 10-20 seconds!!
It feels scary to do it without the wall.
When I do it by the wall my feet never really touch the wall and im doing good but if I do it away from the wall I can’t do it and when I finally do do it I fall but I can save my self from falling on my back SOMETIMES
.
Can somebody help me?
