Hi Ladies,
I am also one of those mums that only want one child. This is not a decision I made yesterday, or after my LB was born. I always thought of only having one child.
Reasons: (note, this is not to say that my reasons are correct, but this is just how I feel!

I actually do not think I can handle more than one child!

Although I love my boy to death, I find motherhood extremely hard... I have always been a bit on my own mission. I like independence, and don't like to give somebody feedback on my life constantly. Also, if I want to sleep/work/eat, I do so..So, I think that's why I only got married just before 30. Obviously this totally changed after the birth of my son!

I see a child as a special gift from God, and I embrace this so much, but like I said, I think this was my first and last child. Its so heartbreaking for me when he is for example sick!!! Imagine I have 3 kids that's sick/unhappy/get bullied at school!!! Okay, I know I am not building the nation, but just really want one child..!
Also, the responsibility is huge. This child is me and my husband's responsibility until his 18-at least- so I will dedicate my life to make sure I do the best with his upbringing and be in a position that is always financially looked after.
I suppose we are going to be one of those families that will always take "the friend" along on holidays!
