Every so often, I have to remind Davis that he is not the mom... He gets "big brother syndrome" and adds a very mommy-esk tone and then lets Jackson know what his current offense is: "Jackson, you KNOW what happens when you fuss..." or "I am not going to let you have this banana unless you ask nicely..."
I let Davis know that I am the mommy and that his job is to be "the encouraging older brother." Sometimes, when he is being particularly thick with mommy words and tones I tell him tongue-in-cheek that he is going to put me out of a job - that he better stop doing my job or I will have to find another family that needs a mom since he is doing my job for me.
So tonight, I had my hands full with my two younger ones. They were both fussing at everything in the worst ways. One was so out of control that I eventually had to put him in the shower - fully clothed - and cool him off. In the middle of it all Davis, who was quietly playing trains while I was alternating between tantrumming children, said "I guess they are making sure you have a job today!"
