He rules the house

So my 4 year old thinks he runs the show around here. He's very helpful, I'll give him that. Always letting me know when Collin gets into something or if Dominic is eating something he shouldn't have. I'm very thankful. However, today I am telling him we need to brush his teeth, he needs to wash his hands and I'm going on and on. He looks at me and says "mom, you need to settle down right now." I'm so shocked by these things that he says sometimes that I just have to walk off and laugh. Everyday something new and so adult like comes out of his mouth. He is always telling me to be patient. I thought we were the teachers of our children, in my case it may be the other way around sometimes :)
