Second, the main responsibility for showing attitude, including understanding and education for the elderly, is the parents of children. There is no doubt that old people love children. Isn't it a good thing that one more person in the world loves your children? Express to the old man that you know her love for children and thank her for her contribution to your family (be sincere). At the same time, emphasize your own educational ideas, and discuss what to do when there are conflicts in educational ideas (tips, guide the elderly to say it themselves, and finally choose a method acceptable to both of you). For example, even if there are conceptual conflicts, when you educate your children, your mother-in-law and the elderly will temporarily avoid each other and discuss each other's ideas separately later.
Third, a passage from the Tao Te Ching is attached: "We are new, we have less, and we are confused." The expression and content can be expressed tactfully, and it is easy to fold if you use too much force. Two people are often in a lose-lose situation, so it is better to learn the elasticity of water, drop water wears away the stone and slowly penetrate into her.
Ps: You still have your husband as an important weapon. You should use him as a blending agent.
