Now there are many different ways to handle a restless teenager. First you have to ask yourself how that teenager whom ever it may be is treated on a regular. For ins-tense as a parent do you give your teenager a-lot of attention or do you barley give him/she attention. If its the (a-lot) option I would ease up and seem less controlling or worried let them feel like they can breathe and if you chose the (barley) then do the opposite shower them with affection just not to much.
