above all, it's crucial that parents have room to breathe

"The elder brother is four years old, and the younger sister is two. Both my wife and I work, and on weekdays her burden outweighs mine, so for the weekends I want her to rest at home as much as possible. She deserves it for the days off.
Otherwise it's risky. When stress accumulates, there will be consequences, both for the children and the parents.
Without switching on and off, everyone's going to get worn out. We have to have balance. Well, there's no one right way though.
It's okay if you're tolerant of stress, but my wife is rather vulnerable.
She was aged when she gave birth to the second child. At thirty seven or eight.
So I think earlier the better. Giving birth to and raising children. The grown-ups around me always used to say that having children is tough, so I was going easy and then before I knew it I was in my thirties. If children were this adorable, they should have let me know earlier!
There were only negative words like 'You can't raise children. They cost you too.'
It's ideal that we have children when we're around thirty, but you know, we're not sure if our plan's going to come true.
Well, I hear from my friends who are mothers that it's a bit tough when you have active boys in a row. They say it's tough for you mentally as well. It's astonishing how people used to raise like five children in the past. I guess that was the common family structure though, with grandparents too.
I want my two children to get along well with each other, but above all, it's crucial that parents have room to breathe. Sometimes fathers and mothers give harsh or mean words to children. If we get warped, children will be the same. We first have to be straightforward.
Then, give them environment and let them do anything they want to. Without the parents' interference. It's often necessary to put them in tough circumstances too. That's my ideal for parents."
