It's not particularly about bonding it's about daily quality of life and ensuring kids aren't tired,feel secure,have time to do the things they need to do(homework, free play,exercise,relaxing,just being etc),aren't continuously battling for attention or time alone etc.It's about minimising stress and enjoying time as a family that isn't just expensive days out.
The fact is working life is a whole world away from the ideal Xenia bangs on about.It involves stress,zero time,no private school,no nannies,no cleaners,exhaustion etc,etc and more importantly parents missing their kids/kids missing their parents.
However hard you work the fact remains the vast maj of us won't be on 100k but a lot less.
Helping parents to take time off if they want it should be encouraged as should the provision of flexitime,reduced hours when they return.
