Safe and Secure
It's an evolutionary instinct to feel safe. In fact, staying close to our mothers and our tribes is one of the reasons why we've survived so long. You can see this instinct in our children - how they stay near mum and dad so they feel safe before venturing out to make new friends and try out new things. If we don't feel like we have a safe, secure and grounded base, we can't develop, grow and meet challenges. It's why having a stable and secure home life is important for a human's development. It's why governments (used to!) invest in programmes such as Sure Start and No Child Left Behind.
