Food...and poop

So since I have started nursing Gideon, I have been SOOOOO hungry. I feel like I start eating when I get up in the morning and don't stop until I go to bed at night. The only problem is I still get hungry right around 5 or 6 am when I am up feeding him. It seems no matter what I eat, or how much, I cannot get enough. For example: tonight I had 2 pieces of pizza, a breadstick, a vitamin water, and a bowl of cereal for dinner. And now 45 minutes later I am hungry AGAIN. I feel like I didn't have any dinner...

Apparently Gideon feels the same way too. He will take a good nap or two in the morning and then catnap and eat like crazy for the rest of the day. Then he takes a nap in the evening, and then eats and catnaps like crazy until 1 am. And then he goes to sleep for the next 3-4 hours. I feel like all I have done today is plug the little dude in, burp, change a poopy diaper, cuddle for a few minutes, then when I go to lay him down he wakes up again ready for more food. I must be a human cow or something - and that makes him the pooping machine. In the two weeks he's been here he has gone through 120 diapers. I hear it's normal for newborns to poop all the time, but I don't remember that at all from the other kids.
