It is a trait of a person who likes to take care of others. A Caregiver is the appropriate counterpart of a Little. Just as the childlike parts of a Little are part of his personality, caring is part of a Caregiver's nature. It is not a role he slips into, it is just who he is. He generally loves to do something good for others, to spoil them. He always has a sympathetic ear and takes care of those around him. But especially, of course, for his partner. He loves his Little unconditionally and just the way she is. Above all, he also loves her childlike traits, with everything that goes with them. This means that he not only tolerates her childishness, but appreciates it and doesn't want to miss it. He looks after his little one, cares for her, guides her, takes her by the hand, supports her, encourages her.
For example, he puts her to bed at night, squeezes a soft toy into her arms and reads to her – because that's what he wants, and he wants to do something good for his little one. He enjoys doing childlike things with her, like watching cartoons, doing handicrafts or even going to the zoo. He supports his Little in everyday life, in typical adult things. But he does not aim to do everything for her. He wants his partner to develop and grow. He helps her with job applications, encourages her to go to unpleasant authorities, encourages her to go to therapy if necessary. Furthermore, he manages to give his little one an absolutely secure feeling, so that she feels safe and secure in his presence.
The power imbalance in the relationship is often used for this very purpose. In such relationships, it is usually not about Sub keeping all the rules and keeping the minutes. Rather, it is about the personal development of the Little One. Whether and which punishments are used is up to the couple. Mostly, however, the emphasis is more on rewards – not getting a reward or being reprimanded by daddy/mommy is typically bad enough for a Little. Typically, a caregiver has somehow remained a child himself. This of course helps him to enjoy his Little's childlike features and to participate in childlike things himself. Caregivers are typically also very enthusiastic, love Disney films, like to be silly or have a huge Lego collection.
But equally, a Caregiver loves their grown-up side too. After all, a Little is not just Little, but a person with many facets. For example, he loves to philosophize about the universe or have heated political discussions. They go out together elegantly dressed, she is quite the lady, and he is the gentleman at her side. But a caregiver can also be weak and needy sometimes and let his little one pamper him.
