parent&tot swim 和 Family swim 有什么区别吗？

看看这个吧，基本上，parent-tot swim 是家长带着baby游，Family swim 是大人和孩子一起游，不一定是baby。

Parent-Tot Swim Class
Introduces children (6-months to 4 years) to the water with the support of a parent. For more information on parent-tot lessons please contact: Ed Martig at e-martig@northwestern.edu.

Here at Family Swim School, your child’s comfort and safety are first and foremost while they are led through their 30-minute lesson in stroke development.。。。
