Wow, you hit the nail on the head. My daughter is not the youngest but everything else you posted = 100%.YES. There is usually a long-established clique of moms, and your child will struggle to build relationships with teammates if you aren't friends with their parents. What can make things even worse is if your child is the youngest--then she will likely have no power and become the punching bag for the older girls. Double worse if your daughter is talented.
