Sleep Training - What's the Hardest Thing to Write?

The sleep training entry was my very hardest to write. I really wanted to be so careful in every single word that I chose. Even if you don't do any kind of baby separate from you, any kind of crying method, just by keeping your voice low and keeping the light slow, that is sleep training also. There is no one who is a respected expert who suggests that young babies be left in their cribs for long.
