Also...for a young child I look at what comes after the computer time.
When I was teaching I had a student who just never wanted to leave the playground after recess. His only other "love" was lunch. So I finally moved recess to directly in front of lunch. It was the only activity powerful enough to entice him to run to line up.
So sometimes creatively scheduling the activity that follows the one that is highly attractive to also be a highly attractive activity helps. I would never schedule bath time directly after computer time with my one son because he HATES baths. So bath first, then computer, then I read aloud with him (highly sought after activity).
"Eat your peas, then you can have your ice cream"...behaviorists call this the Premack Principle.
