If it looks like a bad idea, it probably is a bad idea.
The UK media are getting hysterical at the moment over a new fashion called baby yoga, specifically about a video on Facebook. Videos are appearing on social media such as YouTube that show babies, including newborns, being twisted and thrown in the air, which many observers consider dangerous.
Rather than be carried away by emotional hysteria and mass opinion, I watched one of the videos of baby yoga objectively, and using my common sense, I could see that baby yoga is a dangerous activity to subject a baby to.
Firstly, as a naturally clumsy person, I could never trust myself holding a baby, let alone throw it around in the air. Common sense tells me that accidents can easily happen in baby yoga such as losing grip or dropping the baby.
Secondly, the people in the videos doing baby yoga are probably experts, and most people who might copy the experts are amateurs who would do harm to their baby if they tried this activity.
Thirdly, a baby swung around like in the baby yoga videos is subject to major forces on its vulnerable body, predictably risking serious injury or death.
Fourthly, the babies in the few videos I have seen did not appear to enjoy the experience. There are alternative yoga exercises with a baby where they appear to enjoy the interaction, and there is low risk of injury.
Common sense is a form of wisdom, if something looks like a bad idea, it probably is.
