How many times has some kid come running up to their mom with something sticking out of their head, or a gaping cut, or blood coming from some unseen source? When injuries and blood occurs, kids usually run straight for mom, right? (Mine still send close up shots of their wounds in a text message, even now that they’re adults).
Raising kids inadvertently contributed to my ability to describe a bloody wound, stitches, infections, and things that most people don’t want to look at, but which mothers are forced to, and it includes those times when mom is the only one who will stick the nozzle of the antibiotic ointment tube into the abscessed wound of the beloved family feline. These are the experiences, when remembered and repurposed for SciFi story writing, make the reader experience that “ewww” factor which is exactly what we’re after, right?
So, if you aspire to write anything with gore in it, love and hug your little ones when they get hurt, patch them up, then journal your experience and what you saw. You might be able to use it someday. While this might seem heartless to some, just remember, most kids hurt themselves, and most of them live through it, then later you can tell them how their experience contributed to your story. After all, they may as well get some mileage out of that scar they received while testing out their homemade, brakeless go-cart with no steering.
