I had mastitis several times with each of my children when they were newborn. Dd2 has started self settling the last couple of nights (hurray!! I can sleep for more than 2 hours for the first time in months) but by the morning my boobs are soooo full and sore! Is there anything I can do to help avoid mastitis? She went to bed at 7 and already one boob feels rather full. I know it will take a few days for my body to adjust to the change in feeding patterns.
