Does seeking forgiveness stop a mother's supplication, knowing that she regretted it?

The Prophet, may Allah bless him and grant him peace, forbade supplicating against oneself, one's wealth, and one's children. If a mother supplicates against her child, she has erred, and she must repent, seek forgiveness, and feel remorse. It is hoped that Allah will not answer her supplication. She should frequently supplicate for her child with good things. As for the repenting child, he should regret his disobedience, treat his mother kindly, and frequently seek forgiveness.
