How does multiphase sleep affect the brain?

At midnight, I woke to my baby crying and his wailing booming from the monitor on my bedside table. As I stumbled into his room, the buzzer rang, indicating someone downstairs was trying to get in. When I wondered who in their right mind was going to visit a newborn's parents at midnight, I looked out the window but couldn't see anyone, thought it was a prank and ignored them.

At 3 a.m., I woke up with a start, again to the sound of his screams. In the hallway I met one of my two dogs, Monkey, who was crying and walking up and down. Click-click-click your nails on the wooden floors. When I wondered why, I heard a knock on my door, looked through the peephole and saw a policeman.


"So there's someone home," he said as I opened the door and squinted in the fluorescent hallway lights. "Do you know where your dog is?"

"My dogs are in here," I replied defensively.

"Are you sure?"

I wasn't sure about anything. I wasn't even sure I had dressed when I opened the door, although luckily I did. Since my son was born six months ago, I've had the rough transition from one single phase Sleep plan where I slept in a large block overnight, to one multi-phase Made a sleep plan or fell asleep in small fights several times within 24 hours. I was tired and blurry the whole time.

As the cop twinkled downstairs, my sleepless brain struggled through a slow rewind of the evening: I remembered getting home from the vet and having a very tired baby, a diaper bag, a car seat, and two 75-pound dogs for three Flights had towed stairs and, I thought, into the apartment. I remembered putting the baby to bed and then collapsing on the couch with my husband and a frozen pizza I couldn't remember before falling asleep. My husband woke me up to go to bed and then ...

"Hey lady? I was holding your dog downstairs. It was loose in the hallway. Your neighbors downstairs came home and they started barking through the front door. They tried to hum and call you, but you never answered, so answered." she called us, "he paused and then said with a grin." I need to know: How do you not know if your own dog is in your apartment? "

Good question, but I didn't mean to explain the phased sleep deprivation to him while my confused dog waited downstairs. Rest assured, you'll find the answers on the following pages.
