S.L.
Hi S. G. I went through the same thing with my 2 children, but mine were older and I used old fashioned bribery, I just had to find what worked with each child, with my daughter I found little toys that were on the clearance racks and each time she went she would get to pick one, this did not work with my son, with him it was a brand new "Sponge Bob" bathing suit that I told him if he went potty in it, it would have to go in the trash. I this is helpful, just my experience
