How are things related to swimming education in different countries? In the Netherlands swimming lessons are a pretty basic parental 'requirement'. Former decades had school swimming, but that fell out of grace due to costs and liability issues. I've been taking my sons for lessons for what feels like ages already (about 1.5 years weekly, now twice a week, with about max. a year to go). At that point they are pretty good swimmers, even fully clothed including jackets and it's my responsibility to keep practicing. How is that internationally? It feels quite irresponsible to take children without training to swimming pools, but that might my local customs focus. Swimming is a hard technique to master though.
