My 11 year old has sprained his thumb in the playground today I have been lucky as he very rarely ill and I can't remember the last time I gave him any calpol or nurofen. I picked up a bottle of nurofen on the way home from school and it only had a dosage for 7-9 year olds as the top dosage. I have ibruprofen here so looked on the box only age 12 and above. So what am I supposed to give an 11 year old then?
