Not the Boss of Me T-Shirt
Your child is at that tricky age where the simplest task (taking a nap, eating real food, getting into the car-seat, getting out of the car-seat) becomes a battle of wills. You can't really control your little commander-in-chief so you might as well get them a T-shirt that says it all, "You're Not the Boss of Me". It makes an excellent shirt for daycare, summer camp and wherever your little monster may encounter would-be authority figures.
