Watch our words

This morning while he was taking a bath, i was reminding him all the steps that he needed to do and was nagging at him if he misses one step.
He said to me "Please don't push me to my limit!" It was the same statement i used to him two weeks ago when Albert and I was having some mother-child argument. Lesson learned don't use words/statements that you don't want your child say back to you.
