i read that babies have natural swimming instincts too. So the earlier you start teaching them the better. a person who doens't know how to swim technically just forgot how to swim according to biology.This is so sad.I know that family is hurting.
You gotta teach your kids how swim with a regular diaper( it soaks up) and fully clothed when they’re 9 mo-1 year just in case. Kids are really really fast and smart. You can be using the bathroom for 5 minutes and they can unlock the back door , unlock the pool hinge ( which are supposed to be child proof , but kids are smart) and jump in
Most human babies demonstrate an innate swimming or diving reflex from birth until the age of approximately six months
