I come originally from a family of 4 (2 brothers and a sister) and then I have a younger half brother. DH is from a family of 3 (brother and a sister). We always sort of thought 4 would be nice but never actually set it down as something we'd stick to. After I had Paige I wavered from knowing I wanted another one, to being happy with 3 and then knowing with certainty I wanted another baby. DH said during my pg with Paige that was she a boy, we would stop, but then after she was born he was non commital either way. Just before we decided to TTC this bub, he said that he would regret not having another one (typical, it was during one of my "I'm done" phases LOL). And now I wouldn't have it any other way. No doubt we will have tough times financially but I just can't imagine not having this baby in our lives.

Re the comments about having 3 incase of the worst possible senario, I think it stems from the whole 'heir and a spare', where families had to have at least 2 sons to be able to carry on the family name etc in case one didn't live past infancy kwim?
