I haven't read all of this thread yet, but for minors, there's a number of bones that will affect the way they develop. If she's got an injury in one of these growth bones, it could have very significant impact on her in the years that follow. I broke both of my wrists when I was sporty as a teenager. There was some concern prior to my X rays that if certain bones had been affected, that they can fuse and prevent a healthy range of movement heading into adulthood. Fortunately that didn't happen and I can still mastur..... I mean operate machinery and stuff properly. And I don't know what if any impact the injuries will have on the kid. But unless you are an expert on paediatric skeletal development etc, you sound like you've decided that Mam is being harshly viewed in this natter.
I have largely refrained from commenting in this thread. I'm honestly pissed off with JAC over his indiscretion. I'm prepared for the fact that he'll keep his job. But I lost a lot of respect for him when the results came through on his secondary test. As a Broncos fan it's not a great look that you are going into bat for Mam. I'm not trying to attack you. But calling out the family for having the child at home on the couch as evidence that she's not injured is an assumption that you aren't qualified to make.
