"Researchers have long known that animals brought up with a lot of maternal care are less easily frightened and more adventurous.

Please share this info for more people to realize that it is very important to ensure that all mothers in our society have everything they need to be able to nurture their babies both physically and emotionally. All of society will benefit.
