My son's preschool started at age 2 and did not require kids be potty trained at that age, so I saw many kids go through this stage. The majority seemed scared to poop in the toilet or potty. Each kid seemed to get through this a little differently. What worked for our son (took about a month or so) was explaining, in very simple and brief terms, that waiting too long to poop gives you a tummy ache. It also can make it hurt when you do poop. (As an older baby, he had started witholding because of pain.) Then we took the process step by step. At the point we focused on pooping in the potty, our son was not in a diaper during the day and stayed dry at night. However, we put a diaper on him at night so as not to put too much pressure on him -- he didn't understand that he was already staying dry at night. Ineveitably, he would poop within about 30 minutes of our putting on his bedtime diaper. We had him help us get the poop into the toilet, and he flushed the toilet. This was not at all done to shame him or anything like that. We just let him know he was big enough to be responsible for helping with this process. We didn't tell him it was bad that he only pooped in his diaper. We also let him in the loo while one of us pooped, and we showed him the end result, and he could see that we were just fine. We read "Everybody Poops," too, of course. He was already on Miralax for reflux/constipation issues, so then we upped the Miralax a bit, looked for signs of needing to go, and put him on his potty. We explained that often it takes a while to poop. He was confused that he didn't poop right away and thought he didn't have to go. We did have success with sticker charts, and whenever he pooped in the potty, he received a special sticker. After a few weeks, we moved to the toilet. For our son, having s step stool to put his feet on helped a ton. Pooping with his legs dangling down just didn't work. Once he had pooped in the potty a few times, he no longer seemed aprehensive about trying. After a couple of months, he no longer cared about the stickers and just pooped when he needed to. Other people I know took whatever "prize" was promised and placed it out of reach but within eyeshot of the child when he/she was on the toilet. That seemed to help for them. My cousin took a more drastic step with her son that her son's pediatrician recommended. After a day or so without pooping, she gave her son a Baby Fleet glycerin enema. I had to give these to my son once in a blue moon when he was a baby because of his tummy problems. Before doing so, I gave myself an adult one so that I would know what I was doing to my child. It causes some weird feeling, but not painful, cramping (though I would imagine a kid would perceive the discomfort as pain given his/her more limited vocabulary and experience set). And then you go. Resistance would be impossible. My cousin used this with her son and then gave him a special cookie that he only got after pooping in the toilet (for the record, I am completely against rewarding with food or making any food special -- I'm just explaining the process she used). She didn't have to use the Fleet more than a couple of times. Another suggestion is to praise your daughter the first time she poops in the potty/toilet, but don't go overboard. After the first time, keep praise low-key because she needs to understand that pooping in the toilet is expected, not a special event. There are many reasons that kids don't want to poop in the potty -- wanting to control something that their parents cannot control but really want (so don't show how much you want it --take a break for a couple of months if you've already shown your cards on this), feeling like they are parting with a body part, having difficulty with balance and pushing without a step stool, etc. Lots of us have kids who did the same thing. I promise you will get through this!
