I genuinely don't know how to feel about this as I'm shocked. For context, DH and I do not smack our DS(6). I am not here to debate that, only note that it is not how we are raising our son. This has never happened before and we are close with MIL, usually seeing her multiple times a week.
DS is autistic and when he gets overly excited he can be rough in play. When playing this morning he bit MIL. MIL then hit him hard on the back and shouted at him that he should not bite. This obviously frightened him. We tried to explain why to him we don't bite/do our usual discipline but he was inconsolable. He kept hiding behind me and asking to go home.
When I went to help DS get ready to leave, DH called her out on it. He said that he understood that it may have been an old habit/instant reaction, however we do not hit DS and to please never do that again. She said that we can parent how we want, but she will discipline as she sees fit.
DH told me this when we got home and we are both shocked and disgusted. We sat DS down and told him that is was wrong to bite his Grandma but it was also wrong for Grandma to hit him. And that if anybody ever hits him again to tell us right away.
DH has said that if it ever happens again that it will be the last time she sees us, however I now feel very uncomfortable. I would maybe agree if she'd apologised however it feels like a looming threat that she will "discipline as she sees fit". Am I overreacting? Would you give her a second chance?
