no to young at this time. in the event of williams death harry is next in line but now that he's renounced the throne , i'm not sure who would take over if william dies before his son is old enough to take over. the king or queen has to be over the age of 18 to ascend to the throne.and considering his son is 6 years old............... if charles dies then william is the next in line as it is. if william dies princess anne is next in line and if she dies prince andrew is out the running now with his epstein scandle hovering over his head. so that leaves prince edward to ascend to the throne. it's a mess as it is now.
