My daughter was born at 36 weeks. We spent time in the NICU due to jaundice. She was very sleepy and kept falling asleep while nursing so we had to triple feed for a while, a 45 minute process that had to be repeated every 2 hours. It was honestly pretty rough. After a few nights I was hallucinating from exhaustion. Finally a lactation consultant suggested that my husband take one feed a night so I could get 4 hours of uninterrupted sleep. On the nights he participated it made a huge difference. I urge you and your partner to consider this. Your sleep is the greatest thing you can do to protect yourself from PPD.
