Yes. On balance, Reiki is dangerous.
Not just for a baby, but for anyone.
Why?
Okay, the fact is, it does nothing. There is no evidence of any kind to show it works. There is nothing there. Nothing is working. If you can prove to me that Reiki works, I will give you my house, my car, my children, my feet, my kidneys and my eyeballs. It doesn't matter if you believe it works or not, in any and every test, it hasn't.
But then, surely, it's harmless, right?
No.
Because it's expensive, but in some countries, it's less expensive than conventional medicine. Or, it's easier to access than a regular GP, so it is actually seen as an 'alternative'.
But, it does nothing, right?
So what happens? If there was nothing wrong in the first place, then you're worse off for having paid for it or wasted time on it.
If there was something wrong, that gets better on its own, you're also worse off for having paid for it or wasted time on it.
If there's something wrong that gets better because you've chosen conventional medicine alongside Reiki, then you're worse off because you've paid for it or wasted time on it.
If there's something wrong that you've chosen Reiki (or any faith-based healing method) to treat, instead of conventional medicine, that could have been cured by seeing a proper doctor, then harm is being caused by this choice.
If you are paying to 'learn' Reiki, you're not actually learning anything. You get 'attuned' to it, basically by someone drawing squiggles over your head with their fingers. But they also are taught that some kind of 'energy transfer' which can be in the form of money or other services, has to take place for this to happen. But nothing detectable is happening.
The con trick is that once you've paid for this, you're invested in it working, so you try to convince yourself that it does.
It's like giving the 'Imaginary Friend Bodyguard Service' money and having them tell you that an imaginary friend is going to be your bodyguard for the day to stop you getting mugged. The chances are, you won't get mugged anyway, so hey! The imaginary friend bodyguard protected you! Until you do run into a real and serious problem, and the imaginary friend does nothing and can't help. That's Reiki, that is.
So, yeah, for these reasons and more, Reiki is not harmless and on balance, does more harm than good.
And before you slate me as someone that's 'closed minded' or not open to alternative culture, I've taken part in Witchcraft rituals in the New Forest and Druidic ones at Stonehenge and Avebury. The owners of the oldest occult bookshop in the world know me by name and make me cups of tea when I drop by. My children have been breastfed in Aleister Crowley's old armchair. I can identify and tell you how to use a dozen different plants for healing purposes.
And I still think that Reiki is a dangerous con trick.
