E.B.
It's a huge decision. I made the decision based on my idea of what kind of dynamic I wanted in my family. I went into it wanting 3, so having the second was not an issue for me--I knew I wanted siblings. When it came time for the 3rd, I thought long and hard about having more kids than I have hands--two was challenging enough! The final decision came when I decided to "try on" the thought of having only 2, and I realized that my family was not complete with 2. I wanted the unevenness of 3, or something like that. Now I have 3, and although I miss babyhood very, very much, I know that I'm done. It's what I thought it would be--the 3-way sibling relationship is a special thing, I think. So I've got it, and I love it with all the pros and cons, and I know I signed up for all of it!
