Our kids don't have everything. By our choice.
I had pretty much everything as a child. I did grow up in America after all. My husband a child of PRL had adventures, not toys.
Years ago we bought a house about an hour outside of the city in a village of 500 people surrounded by farms and forests. A house is an overstatement. It was more likes a collection of bricks. No heating, no electricity, no water, no bathroom, but one hectare of land and peace and quiet all around.
Now the house has new windows and a new roof. It has electricity and water and heating and its first ever indoor bathroom. Ameryka, po prostu. Our kids have a big room, shared, full of books and toys - it is true. They have less than what I had, and more than their father had.
There will be no gaming systems, no iPad per kid, no television sets in their rooms, nothing like that. There will be family bike rides, their own personal flower beds (weeded out by Mom), worms, snakes, frogs, bug bites, swimming in the lake, and family barbecues - emphasis on experiences, instead of things.
I must admit it is often harder for us as parents to say no than for the kids to hear it, especially the parent who had less as a child. Yes, one Coca-cola won't kill them, but today it's a coke, tomorrow a candy bar, the next day a video game. It's a slippery slope ;)
If you know Polish, here is one parent's perspective on the "kids with everything " issue - from a parent who grew up with "nothing".
