I do have a friend that had #3 because she has a fear of one of her children dying and not having the support of another sibling to help them through it.
Wow, that is interesting... and something that I would probably cross my mind too...

Well so far we have 1, and are pg with #2. As far as DP is concerned, 2 is as many as we will be having - and it took years of gentle persuasion to get him to consider #2 as it was.
At this stage, and for the next few years of my life I definitely do not think I am up to raising more than 2 children... but I do have a feeling that once the youngest is in school I might start thinking about it again.

I came from a large family of 5 girls, so was never lonely at home... it was wonderful. However at the same time I never really connected with my parents, and that has affected me a bit - especially the lack of connection with my mother. This was due to the fact that she was always just so busy, and never really got close to any of us on an emotional level, which has affected some of us siblings more than others.
For that reason I don't think I would have 5 kids, probably not even 4.
However, I will always keep my options open, I am only 24 so have many years left in me yet...
