DH and I had a discussion last night about DS not "sleeping through the night" yet. Our approaches to how to get DS to sleep and how quickly to respond to him when he wakes up are starting to diverge a bit. Here is a Sleep Problems FAQ by Dr. Sears.

I don't want him to learn to cry himself to sleep. Here are a couple more relevant articles from Dr. Sears:
