Hairline fracture in newborn

So after my suprize induction yesterday my daughter spent almost 24 hours and Nick you as they had her under observations you to my high risk pregnancy and difficulty during labor apparently V because she is so big she got stuck and they had to pull her out which cause a hairline fracture. The nurse told me that I have keeper swaddled and keep her right arm close to watch her body. I've been looking it up and I know you can get us some bling for newborns and I'm possibly thinking about getting one of those but in the long haul going to have to have her arm pretty stable for the next four to six weeks while it heals and then she starts therapy. This is pretty overwhelming for me because nothing really went as planned ..my induction, the labor, epidural, now the injure...idk what to do any advice
