My initial reaction was to not give Hard Ketones to our kids, because 1,3 butanediol is a type of alcohol. However, considering that butanediol doesn’t have the same intoxicating effects as ethanol, and the 1984 National Minimum Drinking Age Act doesn’t prohibit me from doing so, I let both of my kids (aged seven and nine) take a sip. They didn’t like the taste and never asked to try again.
