The bond between a mother and her child is unique. If the child is a boy though, the relationship he forms with his mother becomes crucial to the his growth as a man, taking on added importance when it comes to his views on women, dealing with emotion, etc. 

A good relationship between a boy and his mother is healthy. According to a study by the American Psychological Association, cited in, "boys who are close to their mothers tend not to buy into hyper-masculine stereotypes. They don't believe, for instance, that you have to always act tough, go it alone or fight to prove your manhood every time you are challenged. These boys remained more emotionally open. Not only did they have better friendships, but also less anxiety and depression than their more macho peers." 

On the other hand, University of Reading research, cited by Science Daily, suggested that boys who have "insecure attachments to their mothers in the early years have more behaviour problems later in childhood." 

In the case of the little boy in this video though, it's safe to assume his relationship with his mom and dad is a healthy one, albeit maybe a little more competitive with his father. Nonetheless, if there's anything to take away from this video, aside from how downright adorable it is, it's that there's nothing more valuable than a loving mother.
