My kid is 6 years old now. She really loves swimming, so we've constructed a swimming pool in our backyard with the help of swimming pool construction Boston. She's good in swimming, but last week, she somehow drowned in the pool and thankfully I was beside her. I don't want to discourage or scare her off, but I'm concerned for her safety. Is there any product that can be worn on her wrist or neck that'll give some sort of alarm in case if she's drowned? If you know any such product, please let me know.
