had such bad PND first time, there is almost 6 yers between by DCs....and not an ounce of depression second time
i knew i would be depressed if we had no more children, whereas there was a chance of being depressed with having another child
so once i got pregnant, went to docs at 6 weeks, said i was pregnant and could they please look after me and keep a close eye, and be proactive...which they were, and my HV was involved too and very helpful..and never had any problems
my PND was triggered by having an emergency c.s , and i was not diagnosed until he was 18 months old, so far too long, ( had different doctor then )
this time, i did all could to ensure the delivery was more positive, and achieved what i wanted , which made a difference
i suppose i was lucky i could pinpoint what started it all, and work to address it second time
and with all due respect to your psych, not his decision if you have another baby, and you will be much more aware this time of things being bad again, as will your DH...
if you do have PND again, your Doc, HV and psych will all be on notice, and ready to jump in and help....
