Is not feeding honey to a baby common knowledge?

I have a question for relatively recent parents: When you were learning to care for a baby, did someone warn you not to feed a baby honey?

At my workplace, there's been 3 reports of infant botulism in 1 year - this is the main risk of feeding honey to a baby, even if it's pasteurised. Babies' guts apparently aren't developed enough to manage the bacteria in honey.

The GPs consider this common knowledge, and are a bit frustrated at having to remind folks of what they consider a totally avoidable risk to a potentially dangerous condition.

SO: did you know this, and told other parents? (As a non-parent, it's not obvious to me, but apparently it's even in the fine print on honey jar labels in the UK.)

Mostly curious as to what is common knowledge, in different circles.
