When I had my first child in 2007, the HV made a home visit at 6 weeks post partum and assessed me for my risk of PND (the multiple choice questionnaire was laughable but that's another story).
I have a 9 week old, and frankly the end of my pregnancy and the birth read like a recipe for problems (pregnancy complications, slightly prem baby by elcs, baby in special care for 24 hours, I had a hemorrage and blood transfusion, we left hospital then baby lost too much weight, back into hospital, baby found to have heart murmur, back out of hospital, I developed an infection in cs scar...)
I have been over the whole story with community midwives, then the health visitors, the GP and the practice nurse. Nobody has asked me if I am OK, or offered any support or anything. I find this really suprising.
I don't think I have PND by the way. I just find it suprising that my experience hasn't caused any concern from HCPs at all.
