My ds is 5, and can be a bit of a handful. He has sn, disabilities, and is more like a 3 year old really. He is still in pull ups, and still throws a lot of tantrums etc. His behaviour has been particularly challenging during these school holidays. He's out of routine, and has been receiving many toys and treats from wider family who mean well, but it's been a bit like Christmas 2, extended over 2 weeks. But anyway, yesterday I was in another room, and my ds was with his aunt, uncle, cousin and my dm. I over heard them saying no about something, and then saw my dm carrying ds to a time out. I couldn't get there straight away, as I was getting changed. I asked my dm what had happened, and she said he was doing something naughty, they told him to stop, he didn't listen, and as she carried him to time out, he hit her and bit her. I asked if she was ok, and she said Yes, it didn't hurt. My sil said Sorry about that, but they had told him to stop. I said that it was ok. This was nothing unusual for ds, except that later on, ds told me that nanny had smacked him. There was no mark on him, but then I understood what sil meant when she'd said Sorry about that. I wanted to ask my dm later what had happened, but I never got the chance to speak to her alone, as I didn't want to ask in front of everyone. But we don't smack, I've never smacked my dc, and she knows this. It's also the fact that she didn't tell me, but I found out from ds. I now don't feel able to trust her, and will no longer leave my dc alone with her. I feel sad and betrayed at the moment. Am I over reacting?
