It sounds like maybe going back to block 1 for poop is the next move? Just to make sure she has the concept down first.
It definitely is so exhausting but I think if you can get past the next few days it is seriously going to change your life! It is so freeing to have potty training behind you. You will get there whether you keep going now or waiting until later, but if you can stick with it now you will get there (eventually). If he has more bandwidth right now, ask him for a break so you can fill your cup (get your nails done, go to movie/yoga class, whatever) and try to come back with fresh eyes.
She can do it!!!
