From my observation, families tend to vary with their extra-curricular struggles. Some families over-schedule their kids and term times are a complete whirlwind of music lessons, sports practises, maths tutoring and swim squad. Not to mention all the life admin of housework and homework.
Other families really don’t have any after school activities or pursuits, which can allow our kids to get quite unstimulated and bored. While we know that it’s a piece of cake for kids to fill all the hours between school and midnight on a screen, we need to consider if this a balanced, healthy life. Are they moving their bodies, seeing their friends, developing new competencies etc?
As I once heard a Judge memorably say – “Kids in sports are not in Courts”. A less catchy version of this might be “Kids in extra-curricular activities are not having hours and hours of sedentary low-quality time on screens, or loads of unsupervised time with their mates, vaping at the park!” Perhaps that's a tad simplistic, but I'm sure you get the point.
If your kids have no extra-curricular activities (especially as they get older – five-year-olds have enough on their plate just getting used to the rhythm of school), you might consider if you can afford to pay for guitar lessons, or encourage them to join a school netball team or get a paper-run.
