Please believe me when I tell you my following remarks are not meant to be mean or anything but supportive. I think just saying it like I see it is the best way for you to gauge where you fit and what you want to do. With the information I give you you'll be able to pick want you think best aides your decision. But remember, nothing in parenting can be hard and fast other than killing and purposely injuring your child is wrong. What ever school of thought you want to utilize keep it at the guideline level and not the written in stone level...there must be flexibility to address unexpected situations...and either way you will have nights that will frustrate you. So....here goes.
Even the absolute most basic entry level study of psychology and child development would tell you that you're asking too much of your wee one right now.
At this point his brain does not understand separation. If he doesn't see you right now, you don't exist. When he's crying--freaking out--it's because he's in a state of mourning and is frightened.
I don't know why everyone chooses the so called "easy" way even in the face of proper science and education. Self soothing by parents not responding is a false concept. We develop interesting and unhealthy "coping" skills when we feel insecure and alone. Sure, they get us through to a point, but they then interfere in proper relationships in other arenas. We're not talking about training a puppy, and if we were we would understand it takes time and commitment. The only way for your wee one to learn true independence is to teach him he is safe, that you ARE there ALL the time even if you don't want to be. You must be the consistency that all other things are based on...he becomes free to explore and grow because you have proven that you are steadfast and immovable...you're like the ocean or the mountain and he's able to use you as his tether but first you must be vetted.
It's our job to respond. It's our job to submit to parenting. It's our job to SHOW there's no reason for concern and display proof of that until they are capable of reasoning it's true.
Think of how you as an adult feel when you ask for help from someone and they simply tell you to solve it yourself when you have NO IDEA HOW. It's absolutely frustrating and if it's important that you get results quickly it can reduce you to tears even though as an adult you have all the tools or access to tools as well as perspective in order to attain what is needed. How is an infant supposed to tackle things the same way?
Read the information from Jean Piaget on capability and development--he's a staple of Psychology 101...as is Pavlov and Freud. Understanding at this point your baby is working hard at simply learning to coordinate his senses...honestly, you are asking WAY TOO MUCH from him. He is INCAPABLE of doing what you want...right now.
Now, you can train your child to stop asking for you, but it isn't "self soothing", it's "giving up". You may be ok with that "giving up" because it gets you off the hook, but in reality the physiological and physiiological effect on your infant's brain and body is quite seriously negative.
If you're even halfway considering the "babywise" method PLEASE consult this website first: http://www.ezzo.info/
Both Ferber (Cry-it-out)and Babywise, see an increase of ear infections, high heart rates, increased blood pressure, increase of stress hormones, etc...and psychologically turn parent from protector to torture/teaser. While parents buy into the reassurance of coming in every few minutes and do nothing but talk to or tap baby in actually it's paramount to waving a bone in front of a hungry dog and pulling it away. In other words it's just teasing the baby and even more cruel than disappearing for the night which is terribly scary and mean spirited.
Also consider that the Ezzo's have no professional training on their theories, have been caught in fraudulent claims of professional endorsements, and have been counseled against by the American Academy of Pediatrics--they are firmly against this method. Keep in mind also that Dr Richard Ferber has contradicted himself in his theory and changed his own line of thinking.
That is not to say if you're at a point of hurting or endangering your child you can't put him in a safe place and remove yourself from the equation for awhile...that is the only responsible thing to do. But for mere convenience putting your child in survival mode in order to make it through the night is a set up for needy, moody, hard to cope with change, shallow rooted children.
You "may" be interested in these articles, too...either to agree with or get mad at...either way, good read.
