We give a sticker an 1 button chocolate for a pee and 2 button chocolates for a poo. I specifically got a dinosaur chart sticker as she loved dinosaurs, but now she is all over Peppa pig, so got 1 from amazon for Peppa.
Stickers and sweets have worked for us as well all about bribery
We have successfully managed to potty train during the day but at night we are still wearing night nappies for now but we did the sticker chart every time he went and we also used Alexa as a potty timer like every 15 minutes so understood when he needed to pee that the potty was the place to go
