Children as young as three and four are still learning how to play with and co-operate with others. They have just learned by that age they are individuals, separate from their mothers, they are figuring a lot of things out, most will be toilet trained by four but are still prone to accidents as their concentration is elsewhere. Their hand eye co-ordination as well as motor skills are still developing, their cognitive and reasoning abilities are still forming, that's enough for most children, they don't need to be thrown into a serious martial arts class.
Playing games, learning to socialise and enjoying themselves are the best types of activities for youngsters of this age. At this age they do need confidence and independence building activities but not ones where they are put into an actual class of anything. Toddler groups where a parent/care attends too are great, singing groups, 'tumbletots' etc which all bring fun into the child's life.
In the UK children start school at four and a half mostly, they are in the reception class, increasing teachers are telling us that children are coming to school not toilet trained, some still in nappies, unable to dress themselves and unable to communicate ( we do also have the over achieving child but more later). If teachers are having this problem how can martial arts instructors teach them martial arts? the problem is the young school age as children were ready for it in past years but a change in parenting skills or lack of. However most children starting school have enough to cope with without giving them formal martial arts lessons ( or any other activity). I have Rainbows which start at five, we meet for an hour a week and do activities which are often 'learning' ones but ones that are fun so they don't realise they are learning, we sing, play games, cook, make things, earn badges, chat and have fun. We strive very hard not to be 'school'. We do have parents, as do all types of groups, who want their child to earn the most badges, to make the best crafts etc etc. I've had them in martial arts, when are they getting their next belt, why haven't they graded etc etc. We've all met
those parents.
We also come to the emotional aspect of martial arts, do we really want to teach three and four years olds how to punch, kick and fight? They manage it very well without been taught to do it even better, they can also wrestle, bite and scratch. They are emotional creatures who are unlikely to be able to reason and talk enough when they are frustrated so will lash out. This means that, however many times you tell them not to use martial arts they most certainly will!
Martial arts should not to be taught until the child has a reasonable handle on the world, can control their emotions enough to be able understand in what circumstances they can use their martial skills. Most of all they shouldn't be taught until they want to learn martial arts. One of the things that most annoys me is parents who bring their child along to learn 'discipline', no, that's their job. it's their job to teach respect too not ours. Children will learn self confidence from achieving in just about every activity, martial arts isn't an exception. People don't need to learn 'discipline' as such they need to learn self discipline, the only kind that counts. Martial arts classes can teach children,
if we aren't careful, to only follow the majority rather than be an individual who can question and find answers for themselves. The huge class with everyone in line following barked orders and with no chance to ask questions isn't a conducive atmosphere for growing minds but many adults see 'discipline' in it.
The question as well is why are martial arts instructors taking on such young children? Is it because it can be a lucrative market?
If it's because an instructor has experience of early years development and wants to start young children on the path to martial arts by playing games, helping them gain motor skills and teaching them to play nicely with others that's great but I suspect its the former reason. Getting children in early and grading them hooks the parents into keeping them at that school.
Instructors who teach very young children, though it really covers all children, should also be aware of the physical effects of training and exercise. They should understand children's physiology not just psychology, this is why I'm a great advocate for taking the appropriate training to be an instructor/coach. In the UK to be a coach or instructor in every sport and activity
apart from martial arts you have to be qualified from a recognised authority such as Sport England, the FA, the RU etc. martial arts only have style self regulated organisations and in many cases instructors have no qualifications, just the belt they graded at.
