Kids are playing organised sports (not just cricket) at a much earlier age now, and yes, it's important that they enjoy whatever it is they play.
I spent many years coaching on the DCB courses over the winter months and most of the bairns that attended enjoyed being there, but there were a few who didn't. Those were the ones who were dragged along by parents who wanted the kids to play cricket more than the kids did. It didn't happen often, but when it did the kids stuck out like sore thumbs, and they just didn't want to be there.
Parents with unrealistic expectations will always be a problem in any sport, especially for the younger age groups. Kids all develop at different rates, they all need time to learn and improve at their own pace. There's some kids who look like world beaters at 11 but fall away later, and others who can't hold a bat at that age but improve their game enormously as they get older.
I've seen kids getting bollocked off their dads after a session is finished because they didn't have a very good net, some kids even went away in tears, that's not right in any sport. We have parents obsessed with averages for 11 year olds, kids that continually change clubs because of adult politics, kids pushed into games they're not ready for. So yes, enjoyment is a major thing for kids, let them enjoy it, after all, that's what kids are supposed to do, PLAY GAMES for FUN.
We all want what's best for our kids, and we all do what we think is right for our kids, that's nature, but every now and then we should take a step back to check our kids ARE actually enjoying the game and not let ourselves get blinded by results and averages.
So, just because " The most important thing is that kids enjoy it" is a regularly used cliche, it doesn't mean it's not right.
