You're doing great! The early days can be so hard. Engorgement seriously sucks, but it will improve.
It took a good few months for my supply to settle somewhat with my first, and 2 or 3 months with my second.
Bub won't be getting too much...not really any such thing with breastfeeding.
Are you a member of 'breastfeeders in australia' on facebook? Or have a look at The Milk Meg.
