My daugther plays in the 5-7 yr old league and they have 4 eight-minute quarters. They do that so the kids get their rest and water. The coach can also swap the players' position 4 times to keep the kids from getting bored and the parents from getting mad if their kids play defense too long.
Soccer is 2 45-minute halves. It's probably divided into 4 quarters in certain situations so that the kids actually LIVE through it and so that you divide minutes efficiently.
Wind sprints every day for the first few weeks, that's all. No water breaks, they need to get tough somehow! Stick it to em! Show no mercy and they WILL respect you. They puke? Make an example out of them. That's all.
Every kiddie soccer game I've ever seen just has a big blob of 20 kids all moving in one direction for about 50 feet, then moving in the other direction for 50 feet. Every once in a while, a kid manages to break off the blob and kick a goal... Ah the fond parental memories! The only thing I remember differently, especially at the 4 year old level, is that about once a game a kid breaks "free" and scores on the wrong goal.
