I'm sorry that you're having such a challenging time. By the sounds of it, though, you are taking all the right steps and soon this will start paying off - so hang in there! As hard as it is right now, the added pressure of starting up a business might be a variable that you do have control over - so maybe give some thought to taking a short recess of a few months - time to allow you to get the other support and services into place. Then once all of that is set up and you have childcare sorted out, you would have more time and energy to devote to your business plans.

Re childcare fees - check what your entitlements are re Centrelink CCB and CCR. Remember that you can organise with the childcare service so that they get the CCB and CCR directly, you then only have to pay the gap that's left over. Once you've done these sums childcare might be more affordable than you realise. Also, re waiting lists, if you chat to the director of the service, they may prioritise your place based on your family circumstances. Family Day Care may also be an option in your area.
