To start this post I need to explore what "Good" and 'Bad" mean. Both links are quite long but I basically cannot imagine Edward fitting the description of "bad". The only description I can see attached to children is "Informal: Disobedient or naughty" Edward has no concept of "good" or "bad". He's a baby, he hasn't the capacity to understand what that means, he is only acting on what he needs. To say he is "good" is saying that is has the capacity to be "bad" and I like I've said before Edward is not capable of either.
I am assuming that the reason we need to label a child dates back from the Victorian era when children were expected to be "seen and not heard, or preferably not seen and not heard" Quote Aunt Emma, Railway Children. (I know this lady is a fictional character!) It comes from the same concept that babies are born evil and need to be broken, by letting them cry it out. If Edward cries, it's because he needs me, not because he is trying to manipulate me or be naughty. Even if those needs are "I am bored or lonely". They are just as important as "I have a dirty nappy". They're his emotional needs, which are just as important as his physical ones.
If you believe a baby is capable of being "good" or "bad" this can surely only lead to resentment?
If a baby isn't doing what you want them to do, then you'd believe the baby is choosing to be like that. And it's only natural to feel resentment towards someone who is going against your wishes. Like I've said before, labels can lead to a self fulfilled prophecy, which is hardly ever a positive thing, surely we want our children to grow up to be themselves, not just a label.
