My boyfriend and I are having a serious problem with fully potty training our almost 4 year old. Our son turns 4 in March and is completely pee trained when it comes to going pee in the potty but absolutely refuses to go poop on the potty. We have done literally everything we can think of to try and get him to poop on the potty. We’ve done his own potty chair, one that goes on the toilet, a sticker chart, candy if he poops on potty, etc. absolutely nothing works. We have no idea what to do anymore. Tips and tricks are SO welcomed. Thank you!!
