That's very true, why make something you want them to love, to be something they want to avoid: punishment. If affection is being used as a form of punishment then it can work in an adverse way as well. My mom used a similar tactic: we had to sit on a chair together or hold hands. Or it'd be a quick thing like "did you just hit her? go give her a hug and say you're sorry!" I think the result was less hugging among my siblings and me and more resentment for hugs/handholding with eachother. Probably because we'd be so angry in that moment when we had to do it. We couldn't wait to split from that chair! We're older now in our early, mid, and late 20s. When we see eachother (which is often! :)), we hug because we miss eachother but it's really kind of awkward between us.. because we didn't like doing it before.
