I had my second child 2 1/2 years after the first, and I also had postpartum psychosis with the first. The second time around, I was put on lithium, under a doctor's care, for a number of weeks before I had a scheduled induction. I had no post-partum problem at all! After several months, I was weaned off the lithium, and have had no problems with this since. You need to see a doctor before you get pregnant to discuss, and figure out a drug treatment plan so that you are at therapeutic levels before the baby is born.
