He's still learning... it is a learning curve.
NO child is perfect about pottying.
He is fine.
Don't pressure.
If pressure, sometimes a child will NOT poop at all.... no matter what. Then they become constipated and need medical intervention. That happened to my daughter. Even if we did not force her.
It just causes "anxiety" and stress in a child. That whole process.
Let him be.
He will get it.
My son is the same way, same age.
I am proud of him.
