this might be more response than you want, but interesting (and kinda depressing when you think about it) fact: there’ve been a bunch of research studies where parents have been asked what they think makes a healthy parent-child relationship, and they tend to like…not answer the actual question because they think they’re being asked what good parenting is, which is not the same. so they talk about things like helping kids with homework and making sure they eat well. children, on the other hand, usually respond to the same question with stuff that’s literally just the definition of healthy relationships generally. affection, honesty, respect, spending time together, sharing interests. and the real kicker is, objectively, we know that’s the kind of stuff that actually has a much better impact not only on whether or not the relationship is strong and positive but also the kid’s overall happiness and psychological health.
so, if you want to write a character who’s really intent on being a Good Parent you’d have them putting massive effort into making their kid Grow Up Right, worrying about shit like if they have The Right Friends and they’re spending Enough Time Outside. but if you want to write a good relationship, just make parent and kid laugh together and respect boundaries and be emotionally supportive, like you would when writing a solid pair of friends or romantic couple.
