It is common for a child to cry and refuse to enter the pool at the class start time, but we have a solution to that. Our instructors and assistants are used to helping with this and will spend a good amount of time trying to get the child into the pool.
In the case when some children are just not ready and may not cooperate, we will request the parent bring the child back when he/she is ready or we may suggest scheduling a
private lesson, or provide simple things that parents can do at home to coax the child into getting into the pool.
