Portugal is a great country for bringing up children in terms of social life. Everybody likes them, have patience for them and give them attention.
You can take young children, even babies, to restaurants and every body thinks it is the most normal thing. Baby cries don’t bother other people and young toddlers can wonder between tables and chairs without diners or restaurant staff complaining about it. And it is the same wherever you go. Children can touch displayed items in shops without a shop assistant standing behind them checking if they are going to brake anything. They are talked to by other shoppers while waiting in the long queue to pay for the week-end shop at the hypermaket. When on the beach, in the park or play ground older children, teenagers and adults always look out for and help ALL the kids, not just the ones they are responsible for.
All in all Portugal, like most of Southern European countries, is geared for bring up children in a calm friendly manner. Except when it comes to playgrounds. There are not many around. Certainly not 10-15 minutes walk away from wherever you live. And if there is happen to be one, it is most likely to have just one swing and a seesaw.
