Ok, my son is 16 months old now and he sleeps through the night and is on a great schedule. I am ttc baby #2 now and starting to panic. I am so afraid of the sleepless nights again. With my son, I used the CIO method and it worked wonders for me. I am now worrying that it won't work for the next one. Am I being selfish to feel this way? Has anyone else panicked once they starting trying for another?
