When you feel bothered or overwhelmed because your child seems to be demanding too much, ask yourself "Who's demanding this of me?"
There's a good chance that a big part of the demand on you is coming from YOU in the form of a "should." If you believe you "should" do something, you are making a demand on yourself!
Remember today that you are free to choose. Whatever the request, you don't have to fulfill it. When you remember your freedom, your child's demands will feel a lot less demanding. :)
