I was going to suggest the same thing, once you have bubs he may want to look at Newstart Incapaciated, and you could then transfer across onto the parenting payment partnered. If you were working previously that may have excluded you from Carers Payment as to be a Carer receiving a Carers Pension you must be provided x amount of care to qualify, someone working fulltime for example would be seen as to not being able to meet the required amount of care. Now that you are not working would it be worth your while to re test your eligibility?
