Sorry, forgot to add that the Australian stuff I've been able to find online is pretty much about postnatal depression and weaning - ie, weaning not long after birth, or in what's roughly known as the postpartum period; and so much of it is about problems establishing breastfeeding, which I feel doesn't really apply in my case. Or about people who are already on antidepressants, which I am not.

The only stuff I have been able to find is from the US.
