Whilst at a friends house this afternoon, my dd and her ds went upstairs to play in her ds's bedroom. Her ds came down with blue bits round his mouth and when we asked him what it was he wouldn't answer. We rushed upstairs to find my dd in my friends bedroom and as soon as she saw us she said 'J did it, not me'. Scattered on the floor were my friends contraceptive pills, we worked out that about 3 of them were missing. Dd assures me that she didn't eat any, and there was nothing round her mouth, but I can't be sure. My friend didn't seem too worried - just gave her ds a drink and that was it, but I AM. What do you think I should do? As I say, dd insists she didn't eat any but I can't be sure. Are they dangerous?
