So, our Oliver is older, and has mostly emotionally damage, not physical, but first we let him talk about it, like you were able to do with sweet pea (and she may need to talk about it more in the future), but then when it was clear that talking wasn’t going to be enough, and he was determined to STAY upset and angry (not sure if he could have decided not to be), then we decided to just do something he wanted to do, while making it clear to him that we wouldn’t FORGET that he was upset.
We ended up putting a small bandaid over our heart and on two of the stuffies hearts, and then we went outside to do things in the yard.
Maybe there is a way you can symbolize her hurt on the outside, so she knows that you GET it, and won’t forget, and then take her to do or see something pleasant—like a walk in nature, or pretty Christmas lights, or whatever you can even glimpse that she might like.
I’m just throwing out ideas while taking a break from skiing, so I don’t know if this is even in the ballpark, but I really want to help her feel better.
