Here's the way I(we, actually, dh agrees) look at it: if you have another one even though you aren't totally sure, you definately won't regret it, but if you don't and you aren't totally sure, then when it's too late you may have major regret! We were done after #3, I knew it and so did dh, I can't explain how but we just knew we didn't want anymore. Well, along came our "surprise" and she was born in late november, 2005. Now we are so in love with her and enjoying her so much that we are actually thinking about #5 I think with the first three being so close (2 years, 9 months from the first to the third) we were so exhausted of all things baby that the thought of ever doing that again was out of the question, but when #4 was born #3 was all ready herself almost three, so we had a break from the work of babies enough to enjoy the pure sweetness of them. My opinion, and it's only my opinion, is that if you think you might want another then you definately do Good luck deciding!
