It's all about love for children, whether it's grandma or mom.
It's just a different way of raising children. For example, grandma is used to feeding her children, and mom's educational philosophy is to love eating. If she doesn't like eating, she is not hungry.
For example, mothers will play mobile phones and tablets for their children, and grandmothers will be particularly uncomfortable.
In fact, there will be a generation gap. My mother-in-law takes care of her children a lot, which I don't like as a mother. Later, I thought it was all for the good of the children. Since she can't change it, why don't we change it ourselves, or you can look after the children yourself.
