Staying back at my parent's for Easter. They are in mid to late 70s. My mum is very energetic and active and always encourages me to leave my daughter with them for a day or two so I have some time to myself, which is always much appreciated. I spent a night in a B&B, got back last night and plan to spend the rest of the week hanging out with DD. However last night my mother told me the the 'hilarious' story of how they had driven DD 5 miles without a seatbelt on. Apparently they had gone to pick up DD from an afternoon at my MILs and had decided to use their vintage car instead of their regular car for the journey. On the way there, DD had sat in the front. On they way back, DD had asked to sit in the back next to Nanna, whilst Grandad drove. They set off before DD's seat belt was fastened and realised in motion that it was defective. Rather than stopping and moving DD into the front seat, they decided Nanna would simply hold DDs seat belt in place over her. DD apparently protested about this, said she didn't feel safe and expressed concern that they would get in trouble with the police, but the journey went ahead regardless. I unfortunately reacted very angrily, telling my parents that a 7 year old clearly has more sense than they do. I have spoken to DD this morning, said she was right to express concern and told her I will tell them never to put her in an unsafe position ever again. Meanwhile my mother has been shouting at me when I asked her to clarify the circumstances, arguing that they didn't think this was against the law, offering no justification for not swapping her into the front seat other than 'not wanting to stop', and currently treating me like I'm getting hysterical over nothing.
AIBU - I'm getting hysterical over nothing
YANBU - Never leave DD in their care again
