Newborn babies eat, sleep, poop, and pee. That's about all they do. They can't tell the difference between light and day. And they don't seem to be too disturbed by noises. When we brought our son home from the hospital, we were surprised to find out that he didn't notice Loki's barking at all. It wasn't a hearing problem, as he still responded to other types of sounds. But Loki's barking didn't wake him up and didn't scare him. He just didn't respond to it at all. Great! We didn't have to worry about trying to shush the dog.
But that has now changed. Our son is about 8 weeks old, almost two months, and we have hit a new stage in his development. He is now sensitive to Loki's barking. It startles him and wakes him up. I knew that this was going to happen sooner or later, I was just hoping for later.
