I think sleep is super important

Some parents over do with the learning, till late night etc

That one has bigger impact than most other things

And audio visual devices at night, also impact sleep

Impacts physical growth, brain growth and regeneration

Studies show brain growth for men finishes at 25 years old

And studies also show the brain need "boredom time" instead of overstimulation

Edit:
There's currently a trend where the kids final height is up to 1 foot less than the expected height due to mobile and iPad use

Lack of vitamin D from lack of outdoor activity

Increased rate of myopia

And markedly short attention span

Brain crave for further over stimulation

Impact real learning long term

Nowadays many gadgets. Not like our time.

Been talking to parents who give their kids gadgets

Some even bring to their room

Next day some of them even sleep in class.

Distracted half the time

Some of them even talking about brain rot tik tok during school hours.

And couple of them already had early puberty but no major growth spurt, probably some growth restriction.

I don't know whether this and COVID brought record failures out during SPM, but this trend is seriously concerning for the nation and the world.
Edit:
On the issue of independence and emotional growth, parents spending time with their kids got bigger factor than kindy or primary school when they are preteen.

You have to build the bridge to teenage years.

They have to be so impressed with you, they respect you and wanna be like you but better.

Otherwise gg
