We knew we wanted 2, but I couldn't decide what kind of spacing would be best. When dd was around a year old we decided to just let it happen and take the decision away. (I know, kind of lame, but it worked.) I got pg when dd was 15 mos, my kids are 23 mos apart. The first few months were really tough, but the payoff is so worth it. We had decided to only have 2 a long, long time ago, but now we're even discussing a possible 3rd, so we'll see.
