What would you do in this Potty Training experience?

i had the same problem with my lil brother i new he could use the potty but he just didn't want to so i went to the 99 cent store and bought a white poster bored and stickers [his favorite] i told him every time he went potty hi would get to put a sticker on the bored he love that he always wanted to pee and poop in the potty i really hope this idea works for u
