Potty training boy....

Kendra • Married Mom of 💝2013,💙2015,💝2017,💙2019, 💝2021 and 3 Angel's 👼👼👼!

I am at my wits end. We are going pee in the potty just fine but I CANNOT for the life of me get him to poop on the potty. We have tried sitting there and different rewards even. It's the moment I take him off and pull his underwear back up he will go hide and poop in them. Please any advice any one??!! I really need him trained fully by August 1st for preschool.
