All of us have to take care of our inner child. It's an important part of our psychological health. I used to neglect my little self just until quite recently. It was reflected in the quality of my life. I felt more fear and anxiety.
Making these soft toys helps me look after my right hemisphere and my inner child. I don't think it's childish to have one of these:). It can serve you as your always ready listener:). It is fluffy so it's nice to hold in hands, which can have a soothing effect.
