Hi. I'm a bit confused as I presumed once your teen hit their 18th BIRTHDAY their child benefit stopped even if they were in their 2nd year of sixth form/college. This happened to my eldest daughter in September 2015 (birthday 21st Sep). However, my 2nd daughter turned 18 last November 2016 and is still receiving Child benefit. Does anyone know the actual stop time? I have a feeling that we have missed out on child benefit for a year when we shouldn't have. Thanks for any advice anyone x
