Congratulations!  You made it through U6 soccer!  You may have a few more gray hairs but over all you are intact!  

Way to go!  You rock!

U8 brings in some new dynamics to the 4 v. 4 format, with the incorporation of throw ins, corner kicks, and goal kicks--and a build out line. 

Again, take a deep breath.  You got this.  All you have to do is keep reinforcing the basics and have fun.  It seems simple enough.  

The good news is:  6 and 7 year olds can pay attention longer than the U6 players could.  They are starting to develop some more coordination and they are loving the game of soccer!  

It doesn't get much better than that.

Keep using the curriculums.  As you can see they work. Praise often, keep the criticism to the minimum (and always keep it positive and constructive) and keep them moving!

If you need anything just touch base with your commissioner or trainer.  They have tons of resources yours just for the asking.
