I know I may get some grief for this but my son is almost 3 and refuses to potty train. I've tried…

My son is 4 and we still have some issues...he will go pee in the potty but not poop sometimes and it's frustrating. However I started using coins as a reward when I first starting potty training. Anytime he went pee he got a penny and anytime he went poop on the potty he got a nickel...I told him once he got to a certain line (vase had a line) we could go get a toy

It's helped tremendously now he's just too busy body to remember to go poop lol

My son is 3 will poop but not pee if you find out anything let me know
