Although such methods may seem effective in the short term, they often lead to significant problems in the long run.

Manipulation in parenting is incredibly harmful to both the child and your relationship with them.
Manipulations don't solve problems; they push them deeper.
Manipulation is deception, and relationships built on deception will eventually be uncovered, leading nowhere good. Through manipulation, we kill the child's individuality. The key mission of parenting is not control, but helping the child become an independent and happy person.
