OP here, Firstly, thanks to everyone who has been comforting me about this. I was pretty upset and distraught when it happened (my whole job being to save and protect people), but now I see it as a learning curve. To answer tour questions/comments; 1) Yes, the centre manager has (finally) granted us a bigger budget for maintenance and we will be replacing all doors within the week. 2) the little girl is A-okay. There were no signs of bruising, swelling, laceration/graze, break, strain, sprain or anything else. I think she was more scared than anything else, but she was dancing around about 5 minutes after I gave her an ice pack, so that's a plus. 3) Yes, everything in Australia tries to kill us. Except volcanoes. We don't have a single active one (and we're the only continent to be able to say that!!!). Again, thanks to everyone for your support. I love my job and I was so scared I was going to lose it, and so worried that I had done this little girl harm. Apparently she just sees it as a cool story to tell at school (her aunt told us this when we made the follow-up phone call).
