Ours is quite similar to yours and we are only expecting baby #1 shortly! This has a lot to do with our loans and stuff though. We have consciously made the choice to (at the moment) have an expensive house in a good suburb as at the time being we can afford to do this(we think this will be a good investment in the long term). In a few years we plan to sell it and buy a bigger house in a cheaper suburb and drastically reduce our loans. The rest of our costs are quite similar to yours though.
