Make a chart and put a sticker in it every time they go

Or do what my mom did on put their diaper on too tight. that'll make them not wanna wear them. ha ha

Show Them How U Go Let Them In The Bath Room With U And Say This How Big Kids/ppl Go Potty The Sticker Chart Is Good And U Can Try A Prize Like For Ex For Every 10 Stickers They Get The Get To Pick 1 Thing At The Dollar Store. I Wouldnt Suggest The Tight Diaper Cuz That Could Hurt Them And They Arnt Really Learning Nething About Going Potty Plus Most Kids Would Just Pull The Diaper Off
