You are very right lindaa!!
No matter you are step-mother or not, what you said is pretty correct!
孔雀妈妈 is a very good stepmother, she wants this kid to be good and she came here to ask the suggestion. She wants to educate this kid to be well-behavior.
Kid is kid, we have the responsibily to educate, help and take care them to growup. So I encourage 孔雀妈妈 to continue your work on this kid. Sooner or later he will know that and appreciate your work on him.
