I think i am being unreasonable! But here's the situation. We haven't let my SIL be alone with our DD now 5, without us nearby. My DH doesn't trust her not to eg give DD sweets without telling us, be safe enough etc. She has previously broken our trust by sharing photos without our permission but also has been really good for the past 6 months or more about respecting rules and boundaries. However DH and I still talked about not letting SIL be with DD5 fully alone. We are currently on holiday with her (SIL), DH, DD5 and DD 2 months. After 9 hrs of travel we arrived. I made dinner, we ate, DH went for a nap and SIL offered to take DD5 for a walk in the holiday park for 20mins. DD was crying and needing to feed after refusing all day. I was exhausted and needed to prepare for bedtime. So without thinking I agreed to the walk without asking DH. DD5 and SIL are back safely and as far as I can tell nothing we would be uncomfortable with happened. But I really shouldn't have agreed to the walk, should I? What can I do to repair the breach of trust? This is a huge deal to DH.
