Right when he says Mama poop, put him on the potty! We have one in the middle of the living room to make it easy. I switched from Huggies to Pampers 360 during the day to make it easy to get him ready to sit. Say good job, praise, and love each time he sits. There are training undies too, so they notice when they get wet, that might be an option too
Definitely seems ready for potty training you got this!
Yessssss he’s ready!
