Trevor Cooper

Trevor Cooper is a character featured in Disney's 2014 live-action film Alexander and the Terrible, Horrible, No Good, Very Bad Day. He is the baby of the Cooper family and was portrayed by Elise and Zoey Vargas.

In the movie, Trevor often cried unless he had his special Bumble Bee pacifier. He was often taken to baby care seminars by his father, Ben Cooper, while the other parents were mothers. There, he had told Ben his first word: "Fommy", which meant father and mother. When Alexander accidently dropped the pacifier in the garbage disposal and that Ben accidently turned it on, it caused Trevor to cry for hours.

The next day, he was taken to Ben's job interview about video game designing. There, he was seen eating a green marker and had the ink all over his face. Later on, he felt awkward that Celia was riding in the same wrecked minivan as everyone else to Nagamaki, only to be making noises through his fist.
