Just so we are clear. The policies regarding the uLittles was set by U.S. Soccer in the PDI (Player Development Initiatives) of which US Youth Soccer/Cal South, AYSO and others are "Youth Affiliate Members" and supposed to adopt. These policies concluded that we want various age groups to get a whole lot more touches (4v4) and play on teams/leagues without competitive pressure from the adults, less travel, no scores-standings, etc. We want little kids to have fun and enjoy soccer and get the adults out of the way because when trophies are on the line, the competitive adults tend to play the better kids over the weaker, pigeon hole the kids into positions too early when they should be learning all elements of the game and getting maximum touches, etc.
The model we are adopting is basically the European model.

There will be many parents and coaches who reject these PDI's under the premise its just not the American way, we want our 6 and 7 year olds to taste the sting of defeat, the euphoria of victory, missed an easy goal or gave up a goal? Cry you little bastard, let the tears flow for being an abject failure. Lose a game? Snacks are back in the cooler and definitely "no sprinkles" for you. We need to drive the weaker, less developed kids from the game as quickly as possible ... we adults need to feel the pride of victory on that drive home, knowing that this little champion sprung forth from our loins to rule the world (or at least other 7 years olds).
Then there will be other parents and coaches who just laugh at the former group and call them idiots for sticking their 6 year old on a team that travels 100 miles to a tournament.
