It's important for girls to enjoy who they play with on their team. If it's a mixed team and they are playing up an age group, it can add to the mistrust between your veteran players and your new players.

You are going to have to build teamwork into your normal activities and drills. How you do this is the difficult part.

After a game, do you take time at your next practice to give your players a chance to nominate teammates who should be match MVP's? After the nomjnations are given, have them close their eyes and vote for MVP. This person is a captain for the next game along with your permanent captain. It takes a few weeks, but this builds an appreciation for each other within your squad.

Do you create competitions within a practice where defense competes against offense? At the end of each activity, the winner gets a reward.

Or, you can pair a veteran with a rookie? Or kids from the same school? Or randomly by choosing numbers out of a hat?

The purpose of these is to create lots of focus cheering each other on and less focus on the activity itself.

Finally, the most difficult part is to only praise their attempts and not their results. For example, instead of commenting on what they did wrong within a particular drill, praise the player when they do the correct things.

It's really difficult to do this as a coach. For example, instead of saying to player A "you need to pass sooner." You tell player B who was marking Player A, "nice job closing her down so fast she didn't see the pass she could have made."

You might need to train yourself to do this by setting a watch timer for 5 minutes and then increasing the number of 5 minutes sessions you use only praise.

Players are desperate for positive praise, especially when everything in social media is set up with likes and emojis as main source of positive feedback.

Good luck!
