Especially the first two years of a child's life are crucial for how the person later forms new relationships as an adult. This is called attachment theory in psychology. Therefore, it is very important for the child to receive love and attention in order to form the most secure attachment possible. Are you aware of how you form and attach in relationships?
In psychology, there are four attachment styles (see below). You don't have to have just one – you may have several, which get activated in different relationships, and they can change over time. So it’s important not to get stuck on just one type, but if we become aware of our attachment style, we can also counteract it and break a bad habit.
