Maybe they mean in the middle of the night? I do remember when I was a little girl (8yrs old) when we got Bandit the dog as a 6 week old pup. He slept in a cardboard box turned upside down with blankets, a ticking alarm clock and a little door and windows cut out of it!! (the predecessor of today's "crate") But all the books and advice was that if he cried in the night, to ignore him. My mom would get up about 3 times a night to take him to pee when he was really small but they told her then not to handle him, ie pick him up, (except for stairs, etc, that he couldnt' get up or down), just to take him out, prompt, praise and then back to bed with no talking or playing! Otherwise the puppy would want to play in the middle of the night and would quickly learn that if I cry, people come and hang out with me!!!

How OLD is that book? Because the book that my parents read when we got Bandit is over 22 yrs old now!!!

Could that be what the book means?
