I was okay, meaning no sleepless nights, no postpartum depression, with my second child. I may have had a little bit of Postpartum Blues (I had a tiny bit of anxiety that resolved in 2 weeks).
With my first child I had PPD and was shortly medicated (Zoloft sample), this lasted all of two months. The biggest problem was not being able to sleep (and for me that was awful). I guess I'm someone that cannot function with days and days of no sleep. I also had anxiety and depression with that, I believe this all had to do with the shift in hormones and lack of sleep, as well as the stresses that surrounded my first child's birth.
This time, there wasn't a lot of stresses surrounding my pregnancy and birth (moving, PIH, possible lupus, possible clotting problems, induction before I was ready, moving while shortly due etc.). This time my only stressor I was a spinal HA, which sucked but was easily remedied. I did worry when I was pregant that I would have PPD this last time. I prayed and took care of myself. I was able to breastfeed, took sleep however I got, let the baby sleep on me, coslept, enjoyed my baby, found all the breastfeeding support I needed and was successful. I think it also helps that I went back to work part time both times after my leave was over. Working makes me feel more human, gives me a break in a sense.
So I'm saying it's very possible to skip the PPD this time, although I've heard it's not the norm.
