Start as you mean to go on.! The Children

Golden Rule nr 1:    Instruction Formal.
      "When the trainer speaks , the children should be quiet & they should not play with the ball" They should also be quickly grouped and hold eye contact with the trainer, whilst he speaks. If the child has something to say, they should put up their hand , and wait patiently until the trainer has finished his instruction. (If the trainer can not make eye contact the group is to spread out and will not be heard by most of the children)
    Informal - chat allowed when the trainer feels it necessary and constructive, we need to hear their thoughts and use the feedback positively shouldn't avoid a little bit of humour - 

Golden Rule nr 2:       Instruction   Short and clear
      "Instruction should be short and clear" Children's attention span is very limited from 5,6,7 years of age and is not much better from 8,9 and 10 years of age. Long winded explanations don't help. 
They want to train/play football, and you only have 1½ hours.

Golden Rule nr 3:     Balls for all the Children.
"As much as it is practical ideally every child should have a ball for himself /herself"  Technical training and ball control exercises should dominate training periods. Short tactical comments are allowed in mini games, but condition training should play no part in training from ages 5,6,7,8 very little at 9,10 years of age, again a little more at 11,12,13 etc etc. From the age of 11 lack of condition at " Elite " level can effect a result .Children use so much energy at school  naturally that they definitely don't need to use valuable technical training time on something that is useless in the early years 5,6,7,8,9,10.

Golden Rule nr 4:         Preparation for training 
" The trainer should be ready for action,. Intensity, variation  of exercises and focus on detail to the individual should be as large apart as possible in each training. The group should be a comfortable size. Ideally 1 trainer to 10 players in the early years. 5,6,7,8,9,10 years. 1 trainer to 16 players maximum from 11,12,13,14 years. The difference is because of a natural development in both the size of the teams and the age groups ability to pay attention to instruction - maturity . (5-a-side, 7-a-side and later 11-a side football.)
In the real world it is not always possible to have ideal conditions , but this should not stop the training from being purposeful and part of a bigger objective-plan.

Golden Rule nr 5:        Quality not Quantity
Don't fill the children's head with to much to think about ., It is much more productive  to let them leave the training with 1 single technical detail in place so they never forget it, instead of a whole heap of shit they will forget , even if you repeat the whole routine a hundred times. Quality not quantity.

Summary of these rules:
From the ages of 5,6,7,8 and 9 years old focus area should be 90% technical training. Without the technical abilities , asking them to perform a function or role in a game is frustrating and disjointed , the team will loose possession of the ball more than they have it , and everything will be left to chance. Development and standards will drop.

                    Start as you mean to go on ! The Parents

Golden Rule nr 1:
                          Be diplomatic , but make it clear from the start who it is that decides. How you do this is up to you as an individual . We are all different. I personally have no problem with telling a parent who adds to a negative atmosphere, to leave the training ground or game, if i think it will be to benefit for the group. If the parent refuses to leave , i have at least shown that his/her behavior is unacceptable. I can also rely on parent pressure from the others who are content for him/her not spoil it for the others.
The most important thing is to remain calm and remember there are children about. I recently for the first time in 7 years lost my temper with an unreasonable father, and i was so disappointed with myself i let him get under my skin i nearly stopped- keep your composure at all times.! no matter how provoking the situation is. The last thing we want to do is scare the kids away.

Golden Rule nr 2:
                        Make it clear you are approachable and not a tyrant, but make it equally clear it should not be in the children's training time or on a match day, the adrenalin is pumping and the situation has not got your full focus or attention, It is much better after a game or in private.

Golden Rule nr 3:
                        Don't beat yourself up trying to please everyone, it's a useless waste of energy. Believe in what you are doing or stop as a trainer.
You cannot work voluntary under others parents threats " If Peter doesn't get to play in the first team i will take him to another club. Even if "Peter" is a superstar your authority is seriously undermined if you bow to an individual parent pressure. You can always ask politely if the parent is so unhappy they can try another team, as a last resort. You need to use diplomacy but stand firm in your belief. You should be understanding and flexible without compromising yourself.
  Remember most problems can be sensibly solved ,and most are quite trivial to yourself, but not to the parent who is watching like a hawk for any injustice that will effect their child.
