Sure we do; you go on to say the same thing. You're just emphasizing the "we don't know" part, while I was emphasizing the "there might be some risk" part. We do not know that there is no risk, which, given that alcohol use is avoidable, is the point.
Some research is just poor quality.
Yes, that's true. But the belief that alcohol might harm a developing fetus isn't just based on research. It's also based on common sense: alcohol is known to have the potential to damage your body (at a minimum, harm to the liver and the brain is known to be possible). Why put such a substance into a developing fetus if you don't have to?
And then people have different opinions.
Yes, they do. If a person's considered opinion is that their enjoyment of alcohol is worth whatever risk they believe there is of harm to their child, that's their decision. I'm simply pointing out that, to me, it seems like a no-brainer: you're balancing something that's just recreational for you, vs. a possible harm to your child.
Parents will find it hard to find this information.
That's true of many aspects of parenting, yes. Which is why, as I said above, one shouldn't rely solely on that kind of information; one should also apply common sense.
Let's not forget that parents tend to be sleep deprived and thus cognitively impaired too.
The decision whether or not to use alcohol while pregnant does not have to be made in a cognitively impaired state; decisions like that about how to care for a child should be made before the situation becomes acute.
Plus, the sleep deprivation usually comes after birth, not before, doesn't it?
