you accused your brother of abusing and hurting a child. pretty strong words. i'd be pissed at you too....and then your family jumped on the bandwagon as well. it's not funny, and it can escalate as you now see.

I don't know how old you are but perhaps YOU should have given more thought as to what you were accusing him of doing. kids cry sometimes when you pick them up. for no reason. or sometimes maybe if they are picked up slightly roughly or too roughly, when did this incident even take place? hurting a baby name Jay that my mom had babysit a long time ago. if it took place a long time ago, why even bring it up now? what was the point, other then to cause issue with your brother? and what did you expect his reaction to be? you just accused him of harming a child???

the best thing I can offer now is to back off. leave him alone. give him space to calm down and decide if he wants to interact with you again and how., I think you have said more then enough. it sounds like this is a huge issue to him, it make be some time before he comes to peace with it.
