The Teen Years...

The teen years are almost upon us. My oldest is getting so mouthy. His favorite sayings are you're mean, you're crazy and I don't have to do what u say. He is so rebellious lately. Just when u think u have them mostly able to control their emotions (well except for when it comes to school work) then hormones rear their ugly head. My son will be 13 in September but he has the BO and the zits and the attitude so he may as well be a teen.  They have also had a bad cough for almost a month and nothing the dr can do. I am trying some vitamins and trying to kick it out though.  Are the teen years generally worse with kids with autism or just hard in general?  I think the younger one, 12 years this year also got signs of puberty (worse BO then his brother, zits and blackheads)  He  is being more emotional too but he is a whiner and cryer.  My oldest one is a yeller. How did things change in the teen years for your kids?
