T.T.
I know exactly what you are going through. My 3 1/2 yr. old daughter went through that as well. She was pee-pee trained completely almost a year ago. But, the poo-poo in the potty we finally completed about 1 1/2 mths. ago. My daughter just would not do it. She made her self so constipated it worried me so much. I was told to give her mineral oil in either her drink or mix it with a soft food. This did help so it went more easily. But, she was afraid of the potty when it came to poo-poo. I actually would have to hug her while she did it. And now she's much better and will tell me she needs to potty. I also started giving her a treat everytime she did go. I went to the dollar store and bought some stickers, little books, and other small toys. That also gave her a good incentive. Good luck!!!!!
