@candyquilt-- I'm not an expert on this topic but I don't think so. I think that security and survival are the most important factors affecting development of infants. But as infants grow, their needs also change. Security is not as important for a toddler as it is for an infant. And when a child starts going to school, interaction with friends and teachers, social structures and rules also start playing a role in development.
So childhood development is a very dynamic process that is constantly changing. At least this is how I think about it.
