At one month Zachary weighs around 9 lbs. He's getting a lot longer too , already growing out of some of his 0-3 mo. clothes. He is growing pretty fast and that makes me happy. The newborn stage is a pretty rough stage for me. I think it's pretty rough for him too. We're a little (a lot) sleep deprived over here which is hard on everyone, but we're slowly getting used to it. He's sort of a fussy little man, and that's been hard for us- poor little guy. I was able to get a picture of him while he was awake and not fussing. 
Zach really is a sweet little guy and the kids really enjoy him around - not just because they get away with everything now that I don't have the energy to get after them.
Tyler likes to just look at him, although if he spits up, Tyler will physically step away from him with the most disgusted look on his face. He's really bothered by it. Whitney is an amazing big sister, she can calm Zach just by humming in his ear. She asks me all the time when she can start teaching him new things. It's fun to watch her be so interested in him. She's already asked for another baby ( a girl of course) I look forward to the day when they can all play together.
