A big part of that is that family support is institutionalized on a national level in Europe, from parental leave to subsidized child care to more than a single 6-week 15 minute postpartum check up for a mom that just gave birth to ANOTHER HUMAN.
Airport Security – Lots of European airports have separate security lines for families traveling with small children or those who need extra assistance.
In places that don’t have a dedicated family security lines, security will often pull you to the front if you are traveling with small children, especially if they are crying.
I have experienced separate family security lines in Ireland, England, Iceland, and Germany, and I have been bumped in security lines in France, Belgium and Denmark.
