We just had a baby recently, so it's ODS who's mine, though adopted by DH, SD, and YDS who is ours. I'm not 100 percent certain I don't want another. DH isn't getting a vasectomy until we're both sure that we're done. That doesn't mean we'll definitely have one or not have one. Just that we both need to be on the exact same page. Until then, we're doing the IUD thing as a more "serious" form of birth control. I don't know your situation, but wouldn't it suck to get a reversal if you guys changed your mind?
ETA: symbols. Damn you iPod.
