So, we are all guilty of doing it or having it done to us... brainwashing. It can be done in a very healthy and motherly way, though. I choose this method when it comes to teaching my children just about everything!! It just means that I repeat and reiterate a lot, especially when it come to eating healthy, saving money, and being green. My kids, who are 10, 9, and 8, can then make decisions based on what they have heard over and over (and over!).
One of my favorite instances of seeing this in action, is when my 8 year old daughter asked if we could buy some fruit snacks, and quickly said that we couldn't because they are probably hydrogenated! I did not even have to tell her "no" at that point; she was content in putting them back because they were unhealthy.
