In the same way that some adults have higher sex drives/testosterone levels, is it the same with little boys? My 5 year old has always had a tendency to lash out but he can also be very caring and loving. I can tell when we're going to be hitting some bumps in the road because he starts humping the furniture. Then within a couple of days he'll be in trouble for fighting at school! He's been this way since he was 2. Does anyone else have any experience of this? Could I put bromide in his squash!! Only joking but it does worry me that he's experiencing surges in hormones that are way above what other boys deal with.
