Is mothers' complaining about their children, such as "My son is bothering us; he doesn't like such-and-such food," considered backbiting (gheebah)? And is it permissible to sit with them if their conversation does not go beyond complaining about their children? And is a grandmother's statement about her granddaughter, "This one is mischievous and doesn't sit still," considered backbiting, especially if she says it playfully and the child does not comprehend what is being said about her?
