Stalling at Bedtime

Weston has started coming up with creative ways to stay awake at bedtime. All of sudden he has to poo poo on the potty when we put him to bed. Sometimes he requests a book while he is "trying" to go to the bathroom. During the day, Weston NEVER offers to go #2 on the potty. He is still terrified of the whole process and will have a meltdown if we even suggest that he go #2 on the toilet. So we know that he is just tricking us, but sometimes we let him think he has outsmarted us.
