The instructions say from age 12 and she is 10, however a doctor friend told me years ago that it's done on weight rather than age. DD1 is very tall and whilst not overweight, she's not skinny either. She's had a horrible headache for a day or two on and off and 6+ calpol is helping a bit, but I just wondered if I could give her normal paracetamol or is this completely mad?
