To help those of you who may share my passion of ships & sails but may not have done much sailing of your own, I have compiled the list below to help you to understand the differences between different types of sailing vessels.
There has been little long-term research into toilet-training ages in Australia but research from the US and Europe shows that in the late '40s, toilet training was started at or before 18 months. By 2006, the age had risen to between 21 months and 36 months.
Over the last few decades, the mean age of potting training has crept up in the United States and other countries, including Brazil, Switzerland and China, the article said. In 1980, the mean age U.S. children were toilet-trained was 26 months. In 2003, it was 36.8 months. One possible explanation for later potty training is the widespread availability and convenience of disposable diapers, the study authors propose.
