I refuse to use the cio method with my 4month old. What are my other options?

Teach your baby. You are teaching your child what is correct behavior as well as reinforcing certain behaviors depending upon your actions. If you always respond to your child crying, that will teach the child to cry to get what he wants. If you are putting your child to bed and he cries it is best to respond so that you know the baby is ok, but then to put the baby back to bed by itself when appropriate.
