Very informative and interesting video. It is absolutely right that we should not let our babies cry. A new born or under six months of age infant should never be left to cry it out, even just a few minutes of time. They are so young it is their only way of telling us that they need something. Babies this young and older can suffer short and long term damages if left to cry it out too long or too often. This is very dangerous thing and we being parents should take care of this and should not let our baby crying. During their time in womb, babies hear, feel and even smell their mothers, so it's not hard to believe that they are attached right from birth. But as any adoptive parent can tell us, biology is only part of the love story. Young babies bond emotionally with people who give them regular care and affection. So, these two things are the integral part of a child's care. We being parents should give our full attention to our children because they deserve it.
