This is the OP opening post, and he/she does not mention the age of the "little son" nor whether the child could swim or not. Maybe scolding these women for leaving the little son alone on the beach is unjust and uncalled for.
My own daughter Angela, at one-and-half-years of age, almost drowned in a pool, in front of my own eyes, including those of the lifesaver on duty. She was sitting on the steps leading to the water and apparently got on a swimming board that floated to the middle of the pool, where she fell off. I happen to notice a small nose that had poked through the surface of the water and sumerged again. Without thinking twice, I dived into the middle of the pool and retrieved my daughter from the bottom. When we surfaced, she was laughing. Obviously she was too young to realize what was happening. The next day, I hired the best swimming instructor I could find. He was a fellow training the Panamerican Games children's swimming team at the Hotel Fiesta swimming pool. I told him that all I wanted was for the child to defend herself in water deeper than her head, not to learn how to swim. After several sessions, my daughter was able to swim the entire 25 meter length of the pool. Then, another problem ensued. Everytime the then two-year-old child (by the way, she was very tiny for her age) would jump into a pool, all adults in the vecinity would jump in after her, believing she had fallen accidentally, and would drown. She could swim like a fish.
