I think that you do need to consider your financial position when considering children.
I think it depends on what you want to provide for your children too and the lifestyle you wish to keep.
In saying that you will cope the best way you can regardless of how much $$ you have or how many children you have.
I dont think there is a right or wrong answer to this question and it all depends on your love for the children and what you want out of life in general.

We would love to have about 4 children but of course we cant afford a house to put them all in so will probably stop at two. If circumstances change in the furture then we would maybe look as starting ttc again.
