Parents commonly say things like, "You need to put your toys away and get ready for bed."
Such statements put kids in a double bind if they don't feel like complying. Who should they believe, their parents or their own feelings? It's a loss either way.
"You NEED to" is really a euphemism for "you HAVE to." It's a way of cloaking coercion.
If you don't intend to give your child a choice, be honest and state your command as a command: "Put your toys away and get ready for bed." If that feels rude, maybe your feelings are trying to tell you something. :)
You may realize that the real issue is your needs. That would be a step in the right direction, but don't stop there... A shift in focus from needs to desires is the key that will unlock your creativity.
