We wanted to thank the Welsh Ambulance Service staff who attended us. We were on holiday with our daughter who is autistic with severe learning difficulties. She had a very severe meltdown, demanding to leave the accommodation, but too hysterical for us to be able to exit the property or drive safely. We had tried other avenues of help, but with no success, so after 2 hours, as she was getting even more hysterical, we took the decision to call an ambulance. On arrival, the staff A and J talked to my husband outside, and then came in the property. Although they could not give medication, their appearance and calm, professional manner calmed my daughter. They took her in the ambulance and ran some simple checks, which again, gave her a chance to calm and cool down. On our request, they advised her with calm authority that she must travel calmly home. She agreed. They then led us down the road to check that we were OK in the car. We travelled home safely and without incident. We cannot thank you enough. She has never had such a severe meltdown before. We were completely stuck, and in a potentially dangerous situation. The crew were so nice reassuring us that it was fine that we called them to the house. Their manner with my daughter was also excellent, showing great understanding of autism. Please could you pass on our thanks to this crew and management. We are very grateful to them for helping us and ensuring all our safety in a very difficult situation.
