re: European City with 1.5 year old

Our favorite thing to do with the kids easily, was the Pubs and beer gardens in small towns or the country. The ones in the parks in the bigger cities are solid also. So many of them have areas for the kids to be kids. We'd hit them nightly, heck twice a day if available. My wife would sit at a table and talk with locals or enjoy some peace, and our kids would almost always make friends with someone else's.

I'll never forget, my youngest had a runny nose and the Brit parent came and let me know our daughter had candles.

I would say without a doubt overall European cities are probably more kid friendly than the US. Euros are used to living with kids in confined and smaller spaces, so they are more used to supplying kids with activities when in public.
