I think that finances are something to consider when planning kids.. only really to ensure that you will be able to afford to live off one income for the time that one of you is not working and you are waiting for a childcare spot to become available before returning to work... that you can afford to paythe rent/mortgage on a home of a suitable size and all that... but really, you make do with what you have dont you?
I guess it also depends on your lifestyle - do you want to have the best of everything or is second hand stuff ok, do you want to go on lots of holidays etc... I mean, Claire is not that expensive. i think its just that we are earning heaps less now with me not working which was hard to get used to.
We're definately not rolling in cash.. We've got a mortgage, and I am not working, so its just DH's income we live off - and yeah its tight but not impossible - we just have to really watch our spending habits. So i suppose that yeah money is something to look at because you want to be able to make sure you can provide your kids with everything they need. I know that two years ago, we were not in any financial position for me to be a sahm.
