Well the bananas - Supermarkets all have a large barrel of bananas (sometimes apples) which are free to children who are shopping with their parents, they're to eat whilst you are walking round the shop. I suppose it serves lots of purposes, and its not all the crap fruit either. Simple, but very effective.
DS1 is 6 and goes to a Swedish school, they are all learning English there too (starting at 5), and he also receives 2 hours English tuition for himself per week (this is a law in Sweden), as it's his mother tongue. He skis, skates, fishes and swims with the school, and there's only 9 in his class, so it is a great place despite my current grumblings.
As for the wildlife, well we have deer, red squirrels, foxes, pheasants and all manner of birds in our garden regularly. A few kilometres north and I have seen and elk with her 2 calves and also wild pigs with their offspring. You can even go on a wild pig safari! So although we're only 8 kms north of the city centre we are surrounded by woods and water. And there's a ski slope 2 kms away - small but perfectly formed .
The open air park would have been Skansen, which is on Djurgården, which is also where Junibacken lies. It's just a fab place for kids (and adults too).
Well they have outlawed smoking in restaurants and bars now, but overall no. there's not much smoking. Snuss is more popular now.
But of course with every country it does have it's downsides, but not so many that I would want to leave just yet.
