I had a friend who had a terrible time with her first pregnancy. Hard time conceiving, many complications, baby was not immediately healthy, and suffered with PPD. Her husband was very supportive, caring, loving, gave her all the space she needed to heal physically and emotionally. When she was feeling better (close to a year after Baby was born), he gently asked if she could maybe see her way clear to resuming relations, at least for one night. She agreed, although not feeling 100% yet. One brief encounter later...and she was pregnant again.
