Little things, like I always pack my lunch, and don't use the AC in my car when I commute back and forth to work.
Big things, like finding the same size apartment closer to work for a cheaper price (to save for a house), and me not buying hardware or software (the upgrade I bought for the server was mostly donations).
All for the little one. Sure, at times he can be difficult to deal with (although 3am isn't as bad after you've dealt with it a while); the paranoia is something I'm totally unaccustomed to (we went to a friends apartment that has a balcony on the 3rd floor, and I couldn't stay away from the wall cause I kept picturing me dropping Joey off the edge... bleh, I'm cringing just from remembering that).
But, I don't regret the decision in the slightest. If I had to go back, I wouldn't hesitate to do it all over again (heh, and we probably will have another or two children in the end cause of that feeling).
I know some of you have children, some have thought about children, some have thought in the distant future of having children, and some would rather have a frontal lobotomy; but for me, it is the greatest time of my life.
The greatest feeling is when he wakes us up in the morning crying, and I look over the crib at him, and he sees me, he stops crying, smiles and giggles at me. Waking up to that every morning... its unexplainable.
I dunno why I wanted to type this all out... maybe just to share my feelings to others (and for those that have kids to share their feelings). Anyway, if anyone is thinking of having kids, make sure you know how much your life will change (but don't think it'll change to a worse lifestyle!). Pregnancy, itself, is a whole other bear that I won't explain here, but kids are great. If anyone's lookin for advice on havin kids, please gimmie an email or post or somethin.
