Currently going through the same with my little one. She’s great about going all day and even knows she’s got to poop. She’ll go sit but won’t ever poop. She says “it’s too hard” and will get off before she can go. I’m worried she’s holding it in.

My son was the same but it took some time. One day I just told him that there were no more diapers, and that he had to use the toilet. I had to hold his hand the first few times, but after awhile he got the hang of it.

I bought boxes of candy that are 1$, and just told him he could have them when he pooped on the toilet.

He's maybe not ready?...
