DH and i are arguing over how to do cry-it-out right now.

Our pediatrician said to go at 5, 10, 15 minute intervals after straight crying, not whining. DH feels that it has to literally be 5 minutes of straight crying, otherwise he will reset the timer before going up to her. I feel that if she cries, takes a break and the starts crying again, it should all be counted in those "5 minutes".

Who is right?
