Last night I had my first U-8/U-9 practice with my team. I wouldn't qualify the chaos that ensued as close to "controlled." I had them doing simple pass/dribble/receive drills between cones, and then some mixed 3-on-2, 2-on-1 and other scoring drills. By the end of the one and a half hour practice, I was exhausted. I had coached 4 through 8 year olds before, but now with girls mixed with boys at this age, and my son not taking me seriously, I was having a really hard time commanding the children's respect at the outset. I have an opportunity to practice one more time between now and our first game and I need to quickly establish respect from these kids. I'm just not used to these older ones! Any advice would be great.
