Help. My daughter is 12 and previously I suspected she had taken calpol without my knowledge as the bottle was full and a few months later when I went to use it it was empty. I've explained to her how dangerous etc and she said she understood and she hasn't taken it. As I couldn't be certain I left it there. Today I've been cleaning her room and I've found a calopol 'melt' wrapper under her bed. I went to the medicine cupboard and the pack of 12 definitely had 10 left and now only 2 so she's taken 8 without my knowledge or permission. I am furious so I've gone mad, cancelled our plans for tomorrow (which was was looking forward to) and I don't know what to do from here - please help. I don't have a lockable cabinet and not sure I need one with a 12 year old. The medicines are kept about my bed so she's actually going out of her way to get the medicine!!!
