Let's start with the conclusion: children learn to swim at around 6 years old.
Reason A: Children will forget when they are too young-if they only swim in summer, they will easily forget some of them in the next summer, especially children who are too young (referring to 4-5 years old), and parents need to pay for swimming lessons again.
Reason B: Most children study at this age-you will know when you swim over. Children's ability in this respect has nothing to do with their age, but most children who learn to swim are 6-7 years old, and children should be about the same age. Because the number of people in the swimming pool can't be controlled in summer, it is inevitable that there will be a body collision in the water, so that children can bear the collision. If the child is too young, this should be taken into account.
Reason C: Experts say-considering the growth of the body, experts believe that 6 years old is the earliest age for swimming, and you can find literature on this on the Internet.
Suggestion: Children who are too young can play in shallow water first and get familiar with the water.
